Stefan HallerandClaude Opus 5 0fb30cd986 Make selecting a change block reachable without a controller
Focusing the main view is about to establish a hunk selection, and that
happens in a free function shared with the controller that focuses the
main view from a side panel, which has no main view controller to hand.

Stefan HallerandClaude Opus 5 57757a1b8e Let a main pane be named without the context package
The mode of a diff view's selection lives on the context of the pane showing
it, and until now only the controllers that drive the selection needed to
name that pane, all of which have it as the concrete context it is.

A side panel is about to be handed the pane a command was invoked in, so
that it can act on what is selected there — and it can't be handed a
context, the interface it is handed one through being declared where a
context's concrete type isn't available. So the state moves to where such an
interface can speak of it, and the panes gain one: a context that has a diff
selection.

Stefan HallerandClaude Opus 5 81851dcbbf Show a selection in the focused main view
The focused main view could be scrolled but not pointed at: there was no
way to say "this line" or "these lines", which is what every line-level
interaction needs — editing a line, copying part of a diff, and, later,
staging. So a diff main view now always carries a selection while focused,
starting at the first change already on screen so that focusing doesn't
move the view.

The mode of the selection lives on the main context (a single line, a
range from a fixed anchor, or the change block around the cursor); the
selected line and the range anchor stay in the view itself, whose native
range select draws them, so there is no new highlight machinery. The modes
and their keys are the ones the staging view has, including that the arrow
keys step from block to block in hunk mode.

A pane holds something to select only when what it is showing is a diff
with changes in it, which the render works out once its content is final: a
placeholder message is not a diff, and neither is a diff with nothing in it
at all, such as a binary file's or an empty commit's. Whether a selection
is then drawn there follows from the context stack, as it does for every
other view.

A click in the focused main view now has a meaning again: it selects the
line it points at.

Stefan HallerandClaude Opus 5 49a71aa929 Take the focused main view's context by its concrete type
Both callers pass a main context, and focusing one is about to need more
of it than the Context interface offers. Saying so in the signature also
retires the type assertion that was there only to reach ClearSearchString.

Stefan HallerandClaude Opus 5 a6c0da41cb Stop diving into a patch explorer when clicking the focused main view
Clicking a line of the focused main view entered the staging or patch
building panel at that line. The focused main view is about to gain a
selection of its own, which is what a click there should set — and with
the explorers on their way out, the dive has nowhere to go.

Nothing replaces the gesture yet, so for the next couple of commits a
click in the focused main view does nothing.

Stefan HallerandClaude Opus 5 e8f1a969c4 Classify which side panels show a diff in their main view
The focused main view is about to show a selection, but only where there
are diff lines to act on: a branch's commit log or the status dashboard
has nothing to select. Rather than have the main view guess from the
rendered content, let the side panels say so, since each of them knows
what it renders.

The classification is finer than a yes/no because acting on a selection
means different things per panel — staging into the working tree for the
files panel, taking lines into a custom patch for the commit panels — and
those actions want the same one answer as this. Only whether a panel
shows a diff at all is read for now.

Stefan HallerandClaude Opus 5 71cde8ac9f Fold ViewSelectionController into MainViewController
The focused main view is about to get a real diff selection, which makes
its up/down/page/top/bottom keys mode-aware: what they do depends on the
select state the main view controller owns. Keeping them in a separate
controller would mean either duplicating that state or reaching across
controllers for it, so move them to where the state will live. The two
controllers were attached to the same pair of contexts and nothing else,
so nothing else can notice.

Stefan HallerandClaude Opus 5 3af5e7940c Ask diff renderers for OSC 1717 metadata
A renderer that speaks the protocol emits nothing unless it is asked to,
so that its output stays plain wherever it is used outside lazygit. The
variable names the versions we understand.

git is one of the renderers we ask. It has no pager to spawn, and so no
terminal to spawn one in, but it still renders the diff itself — for the
word-diff formats, whose markup nothing else could resolve — so the
request has to be made before we decide a pty isn't needed.

Stefan HallerandClaude Opus 5 2770b2e5a2 Take a diff renderer at its word about a diff line
Where a renderer states which line of which file it is rendering, take
that as the line's identity. The renderer knows, and for a rendering
that no longer looks like a diff nothing else does. Reading the rendered
text stays the way for the renderings that keep a diff's structure, and
for the renderers that say nothing at all.

Which of the two is used is settled for the rendering as a whole, not
row by row. A rendering with records is not parsed at all, not even for
the rows the renderer says nothing about. Its text is no unified diff,
and a row of it can read like one. Under delta, a commit that adds a
test whose input is a diff shows the test's "diff --git a/img.png
b/img.png" line as a row of its own; parsed, that row opens a file
section that runs to the end of the rendering, and every row delta puts
between hunks and files comes out as a header of a file called img.png.
So the untagged rows of such a rendering stay unresolved, as the
protocol has it (spec section 6.4).

Header records are accepted too. This lets a renderer point at a file
with no content lines, such as a pure rename, a mode change or a binary
file: for those files the header is the only row in the diff.

Stefan HallerandClaude Opus 5 7563dc0f52 Rename parsedDiffLine.RelPath to Path
A diff line's identity is about to become recoverable from a second
source, a diff renderer's own records, and a renderer states the path
however it likes — absolute paths included. The field can't promise
repo-relative any more.

Stefan HallerandClaude Opus 5 a7f08990f8 Read the OSC 1717 records a diff renderer emits
A diff renderer that restructures the diff — into columns, or with the
+/- markers replaced by colour — leaves us no way to tell which line of
which file a rendered row came from, which is what acting on the row
requires. The OSC 1717 protocol has the renderer say so directly: it
prefixes each line it renders with a record naming the file and the
line's position in the old and new versions of it.

Attach each record to the cells it precedes, so that a row's records
survive wrapping and the columns of a side-by-side rendering, and hand
them to readers together with the row's text: the two have to describe
the same buffer, and a re-render can rebuild it between two reads.

Stefan HallerandClaude Opus 5 8cd0a0e9ad Decode the path of a diff header the way git writes it
git doesn't just print the path: it terminates it with a tab when the
path contains a space, and C-quotes the whole field when the path
contains anything it won't print raw — with core.quotePath, which is on
by default, that means any non-ASCII byte, so a file called café shows
up as "b/caf\303\251".

Taking the field verbatim therefore gives a path that doesn't exist, for
a whole class of perfectly ordinary file names. The quoting is Go's own
string syntax, octal escapes and all, so decoding it is a call to
strconv.Unquote.

Stefan HallerandClaude Opus 5 2a190fd1e4 Recover the identity of a diff line from the rendered diff
To act on the line the user is pointing at in a diff view — to stage it,
to open it in an editor, to keep the cursor on it while the diff is
regenerated — we need to know which file it belongs to and where it sits
in that file. Only the diff the view was rendered from knows that, and
by the time it's on screen all we have is text.

So parse it back: the view's contents are (usually) a unified diff, and
running them through the patch parser recovers each row's file, kind and
line numbers. "Usually" is why this goes behind a seam, and why it
answers "I don't know" rather than guessing: a diff renderer is free to
restructure what it prints, and a wrong answer here means acting on the
wrong line of the wrong file.

Parsing a whole buffer is a separate entry point from parsing a single
line, because a caller resolving every row of a large diff must not
re-parse a file's section once per line of it.

Stefan HallerandClaude Opus 5.5 4780c8bb72 Use the detailed commit graph automatically in terminals that draw it
The detailed commit graph is only drawn for users who set
gui.commitGraphStyle to 'detailed'. Many users of terminals that can
draw it will never find out about it. A terminal can't be asked whether
it draws a given character, but it does tell us its name and version
when tcell asks for them with XTVERSION at startup.

Add an 'auto' value and make it the default. It uses the detailed graph
in kitty from 0.36.2 and in Ghostty from 1.0.0 on. These are the first
versions that draw all of the symbols. Everywhere else it stays with
the classic graph. This includes tmux, because tmux answers XTVERSION
itself. So far, WezTerm draws the symbols only in its nightly builds, so
it isn't detected until a release has them. VS Code isn't detected
either, because it only draws the symbols with GPU acceleration.

The expected output of the integration tests has the classic graph, so
pin it in their config. Otherwise they would fail when run with a
visible UI in one of these terminals.

Log the terminal's name and version at startup, to make it possible to
find out why 'auto' picked what it did.

Stefan HallerandClaude Opus 5.5 da5b9b54eb Add an option to draw the commit graph with branch drawing symbols
If a branch forks off a merge commit, the graph can't show both lines
in the merge commit's row. The line from the branch's first commit ends
in the same cell in which the merge's line to its second parent starts.
The box drawing characters have no symbol for a line from above that
bends to the left combined with a line from the left that bends down,
so one of the two gets lost. Today the cell shows a plain vertical
line, and the branch looks as if it sat on the merge's second parent
(#5497).

The branch drawing symbols in the Unicode Private Use Area (U+F5D0 to
U+F60D) have a symbol for every way in which lines meet in a cell.
kitty introduced them for git graph viewers like vim-flog, and Ghostty,
Contour, the terminal of VS Code and nightly builds of WezTerm render
them too. Other terminals need a font that contains them.

Add the gui.commitGraphStyle config. Its 'detailed' style draws the
graph with these symbols, and the commit symbols of the set connect to
their lines. Commits are drawn as hollow circles and merge commits as
filled ones. The default stays the 'classic' style with the box drawing
characters, because not every terminal can display the others.

A cell has only one colour. Where two lines meet, the symbol takes the
colour of the line from above. With the box drawing characters,
highlighting the lines of the selected commit clears the cells they run
through. The branch drawing symbols keep the other lines. A cell in
which a highlighted line bends is highlighted as a whole. Where a
highlighted line crosses the vertical line of another commit, it is
drawn over that line, so that it reads as one line. In a cell in which
another line bends, the symbol keeps the colour of that line.

Stefan HallerandClaude Opus 5.5 e5c5a62cd9 Record how lines run through the cells of the commit graph
A cell of the commit graph only records which of its edges are touched
by lines. That's all the box drawing characters can show, but it
doesn't say how the lines connect. A vertical line with a horizontal
line passing behind it touches all four edges. So does a cell in which
the line from above bends to the left, the line below comes in from the
left, and a horizontal line passes through.

For the lines at the top and bottom edges, record whether they run
straight on or bend to the left or right, and record whether a line
passes through horizontally. Nothing reads this yet. It prepares for
drawing the graph with symbols that can show these differences.

Stefan HallerandClaude Opus 5.5 91378b1e8a Stop drawing a line below root commits in the commit graph
If a root commit isn't the last one in the list, the graph draws a
vertical line below it in every row that follows. A root commit's pipe
to the empty tree never terminates, because no commit comes after it,
so it is carried on from row to row. The line also takes up its column,
and an unrelated commit after the root commit is placed to the right of
it.

Drop that pipe after the root commit's row. In its own row, it still
gives the commit symbol the style of the commit. Also, place a commit
that no line leads to next to the lines that go on into its row, not
next to the lines that ended in the row before. Their columns are free
again.

Stefan HallerandClaude Opus 5.5 cee602c029 Demonstrate that the graph continues the line below a root commit
If a root commit isn't the last one in the list, the graph draws a
vertical line below it in every row that follows, although nothing
comes after a root commit. This happens in repos with more than one
root commit, for example when showing all branches of a repo with a
gh-pages branch, or after merging an unrelated history.

Also, a commit that no line leads to is placed to the right of the
lines that ended in the row before it, although their columns are free
again.

Stefan HallerandClaude Opus 5.5 0afb94e97b Lay git's own diff out to the width the layout gives the view
Changing the screen mode renders the main view again, and so does
anything else that changes its size along with what it shows. With git's
own diff, that render laid a commit's diffstat out to the width the view
had before. The graph then wrapped onto rows of its own in a view that
got narrower, and stopped short in one that got wider.

A diff renderer's render is created after the layout pass, since only
the layout settles the view's size, and takes its width there. git's own
diff took its width straight away instead, when the render was asked
for. Create its task after the layout as well.

otherwise it would select the tags that moved up into the place of the

Stefan HallerandClaude Opus 5.5 26ad23a8d2 Offer to update the branches stacked below the current one when pulling
When somebody else rebases a stack and force-pushes it, pulling the
topmost branch leaves the branches below it diverged. They can be
updated with `f`, but pushing the stack offers to push the branches
below along with the current one, and pulling should be symmetric.

When pulling, find the branches stacked below the current one that can
be updated without losing anything. These are those that are behind
their upstream branches, and those that diverged from them only because
they were rewritten. If there are any, show a menu that lists them and
offers to update them in addition to pulling the current branch, or to
pull only the current branch. The current branch is pulled as before.

The decision is based on the last fetch, not on a new one, so that the
menu appears right away. If the remote has changed since then, a branch
might not be offered although it could be updated; it then shows as
diverged after the pull, and pulling again offers it. The update itself
fetches the upstream branches and checks them again, so it never loses
commits.

Branches that are checked out in another worktree are not offered,
since updating them would change the files there.

The branches below are updated before the current branch is pulled. If
one of them pointed into the commits that a rebasing pull rebases, the
pull would move it when rebase.updateRefs is set, and updating it
afterwards would fail. If updating them fails, the current branch isn't
pulled.

Stefan HallerandClaude Opus 5.5 0a99f65be3 Auto-forward branches that are checked out in other worktrees
If a main branch is checked out in another worktree, auto-forwarding
after a fetch skips it. People who keep the main branch checked out in
their main worktree, and work on feature branches in linked worktrees,
therefore never get it forwarded.

Fast-forward such a branch in the worktree it is checked out in, as `f`
does. Skip the worktree if it has changes to tracked files, since
nobody asked for its files to change. Also skip it if it is mid-rebase
or mid-bisect, because its HEAD is then detached from the branch. A
branch in the current worktree is never forwarded. This covers the case
of the current worktree being mid-rebase on a main branch, whose ref
would otherwise be forwarded under the rebase.

Auto-forwarding now writes the same reflog message as `f`
("lazygit: update to upstream branch").

Stefan HallerandClaude Opus 5.5 1b4fc02040 Keep fast-forwarding the other branches when one of them fails
If `f` is used on several branches that are checked out in other
worktrees, the first worktree in which the fast-forward fails stops the
whole operation. For example, an untracked file that the fast-forward
would overwrite leaves the branches after it untouched, even though
nothing is wrong with them.

Try all the branches, and report the errors of the failed ones
together. The checks that refuse to fast-forward any of the branches
still run before anything is moved.

The next commit uses forwardBranches for auto-forwarding branches in
other worktrees, where stopping at the first failure is worse. A
worktree that fails every time would prevent the ones after it from
ever being forwarded. For this, forwardBranches also takes the git
commands to use, since a background worker doesn't block switching
repos.

Stefan HallerandClaude Opus 5.5 245a613762 Auto-forward branches on a worker
AutoForwardBranches runs in the Then callback of the refresh after a
fetch. This is on the UI thread, so the git command for updating the
branches blocks the UI while it runs. This is fine for a single
update-ref, but the next commit adds a git status and a git merge for
each branch that is checked out in another worktree.

Keep reading the branches from the model on the UI thread, and move the
git work to a worker.

Stefan HallerandClaude Opus 5.5 ef00e18247 Refuse to fast-forward a branch being rebased or bisected in a worktree
The worktree loader associates a worktree that is mid-rebase or
mid-bisect with the branch involved, even though its HEAD is detached.
Fast-forwarding such a branch therefore ran the fast-forward in that
worktree. This moved the detached HEAD and put the upstream commits
into the rebase in progress, while the branch stayed where it was.

Remember in the worktree model when its branch comes from a rebase or
bisect, and refuse to fast-forward the branch in that case. Updating
only the ref is no option for a rebase; the rebase writes the branch
when it finishes.

Stefan HallerandClaude Opus 5 83bff569a0 Allow fast-forwarding a range of branches
After somebody else rebased and force-pushed a stack of branches, every
branch of the stack has to be brought back to its upstream, and pressing
`f` on them one by one is as tedious as the checking out and pulling it
replaces.

Let `f` work on a range selection. The upstream branches are fetched with
one `git fetch` per remote, and the branches that aren't checked out
anywhere move in a single `git update-ref` call. All the selected
branches are looked at before any of them is moved, so a branch that has
to be refused leaves the others alone rather than updating the stack
halfway.

Stefan HallerandClaude Opus 5 78dc65cbeb Fast-forward branches whose upstream branch was rewritten
When somebody else rebases a branch and force-pushes it, the local
branch is left diverged from it, so `f` refuses to touch it. To get back
in sync, the branch has to be checked out and pulled, and for a stack of
branches that means doing it once per branch.

Such a branch has none of its own work in it, though: the commits it is
ahead by are the old versions of the ones that are now on the remote
branch. So when the branch has diverged and none of the commits it is
ahead by is ours, reset it to its upstream instead of refusing. This is
the same state that checking the branch out and pulling it would produce,
as rebase drops commits that the upstream already has.

A branch that isn't checked out anywhere is reset with the same
`git update-ref` that a fast-forward uses. One that is checked out
somewhere is reset with `git reset --keep`, and only when that worktree
has no changes to tracked files, so that the files under the user's feet
change no more than they have to. `--keep` also refuses to overwrite an
untracked file that the reset would bring in, which `--hard` would do
silently.

Stefan HallerandClaude Opus 5 667df9e784 Split fast-forwarding a branch into fetching and updating it
Fast-forwarding a branch that isn't checked out ran a single
`git fetch <remote> refs/heads/<branch>:<branch>`, so git's own refusal
to move a local branch backwards served as the safety check. A later
commit widens the set of branches the command accepts, and for that
lazygit has to make that decision itself.

Fetch the remote branch on its own, updating only its remote-tracking
branch. Then ask git whether the branch is an ancestor of it, and only
then move the branch: with `git update-ref` when it isn't checked out
anywhere, guarded by the hash we knew it to have, and with
`git merge --ff-only` in its worktree when it is checked out there.
Keeping `git pull --ff-only` for the latter case would fetch a second
time.

Fast-forwarding a branch that isn't checked out in a worktree had no
integration test at all, so add one. The second new test covers a repo
that keeps no reflogs, because a later commit starts reading those and
this case has to keep working without them.

Stefan HallerandClaude Opus 5 0d8b18cfb7 Move fast-forwarding a branch into BranchesHelper
Most of the logic of this controller belongs in a helper, and the next
commit reshapes it, so move it over unchanged first to keep that diff
about the change itself.

Stefan HallerandClaude Opus 5 503ca22d09 Generalize CanDoFastForwardMerge into IsAncestor
The function asks git whether HEAD is an ancestor of a ref, and its name
says what the one caller wants to know. A later commit asks the same
question about a branch that isn't checked out, so let the caller name
both refs.

Stefan HallerandClaude Opus 5 3ff0fdbcc1 Dim the divergence of a branch whose upstream was rewritten
When somebody else rebases a branch and force-pushes it, our branch
shows up as diverged, say ↓5↑3, and that looks exactly like a branch
that carries three commits of our own. The two want different treatment.
The first one only has to be moved to its upstream, while the second one
needs a decision about what to do with those commits. The panel doesn't
tell them apart, so users have to look at each branch in turn to find
out which one they are dealing with.

Determine for every diverged branch whether it has commits of its own,
and dim its divergence when it doesn't. This runs on a worker, as it
takes a few git commands per diverged branch, and a branch keeps the
answer from the previous load while a new one is in flight, so that the
display doesn't flicker. A later commit teaches the fast-forward command
to act on such a branch.

The flag says whether this load is the one that kicks off the values
determined in the background afterwards. A later commit adds a second of
those next to the behind-counts, so name the flag after what it controls
rather than after its only user so far.

Stefan HallerandClaude Fable 5.1 9a585bf11e Offer to push the branches stacked below the current one
After rebasing a stack of branches, every branch of the stack has to be
force-pushed, and so far the only way to do that in lazygit was to check
out each branch in turn and push it. For a stack of a dozen branches
that is a lot of work for a routine task.

When the current branch is pushed and there are branches below it in the
stack that have commits to push, show a menu that offers to push them
along with it. The menu lists the branches and how far each of them has
diverged from its remote branch, so that the user can see what is about
to happen. It doesn't show where each branch goes; the branches panel
doesn't show that for a normal push either. Pushing only the current
branch is the second entry. If any of the branches has diverged from its
remote branch, a single confirmation covers force-pushing all of them.

A branch is offered if its tip is a commit of the current branch that
isn't merged yet, it has an upstream that is stored locally, that
upstream is not gone, and it is ahead of its push destination. Branches
without an upstream are left out because a branch that was never pushed
can't be told apart from one that is meant to stay local. A branch that
is only behind is left out because pushing it would move the remote
branch back to an older commit; the lease doesn't catch that when the
remote-tracking branch is up to date.

Each branch is pushed to where `git push` would push it if it were
checked out, using the destination git reports in the %(push) field.
This honors push.default, remote.pushDefault and
branch.<name>.pushRemote without lazygit having to interpret them.
Branches going to the same remote are pushed in one command, with
--force-with-lease when the user confirmed force-pushing; the lease
checks each ref against its remote-tracking branch, so a coworker's
unseen push is still rejected. The current branch joins that command
when its remote-tracking branch is stored locally. Otherwise it needs a
plain push first, for example with --set-upstream, and that option
would apply to every refspec of a combined command; so in that case it
is pushed on its own as before, and the other branches follow in a
second command.

Pushing the current branch on its own still runs a bare `git push`, so
users who rely on push.default or remote.<name>.push for it see no
change. The push is non-atomic, as git defaults to; if one branch's
lease fails, the others still go through and the error names the one to
look at.

Stefan HallerandClaude Fable 5.1 bfb8c91b7b Split pushing the current branch into resolving its destination and pushing
Pushing the current branch has three cases: it has an upstream, it has
none but push.default is "current", or the user is prompted for one.
Each case ends in a push, and the first one also checks whether a force
push is needed. Let the three cases call a common callback instead, and
put the check and the push there. This makes it possible to run the same
three cases with a different callback, so that the branches stacked
below the current one can be pushed along with it.

The check returns false for a branch without an upstream, so the other
two cases behave as before.

Stefan HallerandClaude Fable 5.1 c3b09cebad Add a function to find the branches stacked below a branch
lazygit will offer to push these along with the current branch, so that
a rebased stack can be pushed in one go. The commits panel already marks
the tips of stacked branches, and this uses the same criterion. A branch
is below the given one if its tip is one of the loaded commits of that
branch that isn't merged into a main branch. This needs no git command.
In whole-graph mode the commit list also contains commits of other
branches, but those are marked as merged, so they don't count.

Not used yet.

Stefan HallerandClaude Fable 5.1 6378618544 Generalize the push command to take a remote and a list of refspecs
PushOpts can only describe a push of the current branch. It takes the
branch's name and the upstream to push it to, and builds a single
refspec from them. Pushing several branches in one command needs one
refspec per branch, so let callers pass the refspecs themselves. The
sync controller, the only caller so far, builds the same single refspec
that PushCmdObj built before.

Stefan HallerandClaude Opus 5.5 5196c4fab5 Let users turn off the bold text of the selected line
The text of the selected line is always bold. Some users don't like
this (#2304), but there is no way to turn it off. Setting
selectedLineBgColor doesn't help. Its attributes apply to the text too,
so it can add bold, but it can't take it away.

Add gui.theme.selectedLineFgColor for the text of the selected line, in
focused and unfocused views alike. Its attributes are added to those of
the text, and a color replaces the colors of the text. It is [bold] by
default, so nothing changes unless you set it; 'default' leaves the
text as it is.

Putting bold into the default of selectedLineBgColor instead wouldn't
work well. To turn it off, you would have to replace the whole list, and
lose the color that is computed from the terminal's background.

Stefan HallerandClaude Opus 5.5 ca950181e8 Pick the built-in theme defaults for the terminal's background
Some theme colors can't have one default that suits both dark and light
backgrounds. A gray background for the selected line of an inactive
view has to be lighter than the terminal's background if that is dark,
and darker if it is light.

Give such fields a default for each kind of background. Derive it from
the terminal's background color if the terminal tells us, so that it
keeps the same distance from the background however dark or light that
is, and takes on its tint. Otherwise, assume a black or white
background.

These defaults can't be the defaults of gui.theme. We would then have
to tell whether a value there came from the user or from the built-in
defaults, because only the user's value should win over a background
default. Keep them apart from the user config instead, and leave these
fields empty in the defaults of gui.theme, so that a value there always
comes from the user. Tests ensure that no field has both kinds of
defaults, and that both kinds of background set the same fields.

Start with inactiveViewSelectedLineBgColor: the background mixed with
30% white if it is dark (#4d4d4d on black), or with 15% black if it is
light (#d9d9d9 on white). A gray background shows where the selection
is in a view without the focus more clearly than the bold text we used
so far.

Stefan HallerandClaude Opus 5.5 34c86efc67 Show commits outside the bisect range in faint text
While bisecting, the hashes of the commits outside the bisect range are
black. On a dark gray background this makes them recede, but on a black
one they are invisible, and on a light one they stand out more than any
other hash.

Draw them in faint text instead. The terminal shades faint text toward
its background, whatever that is.

Stefan HallerandClaude Opus 5 679fe58e8e Add a dim text style
A later commit shows the hashes of commits outside the bisect range in a
dimmer variant of the default text color. A darker shade of a terminal
palette color can't be derived, because we don't know what the palette
is, so leave the shading to the terminal and use its faint attribute,
SGR 2. In gookit/color that attribute is called OpFuzzy.

Terminals that don't implement SGR 2 render the text in its normal color.
