Sebastiaan van Stijn 8f7dc04070 update minimum go version to go1.25
- drop support for go1.24
- update vendor.mod to go1.25.0
- update //go:build tags to go1.25

The golang.org/x/ dependencies now require go1.25 as a minimum,
so updating our build tags accordingly.

Sebastiaan van Stijn 13759330b1 cli-plugins/manager: remove legacy system-wide cli-plugin path
commit 4d3a76d71e updated the list of directories
for discovering CLI plugins, adding `%ProgramFiles%\Docker\cli-plugins` for
system-wide plugins.

For backward compatibility, the `%PROGRAMDATA%\Docker\cli-plugins` was kept,
however, this location is no longer used, and not generally recommended for
storing non-data content (such as CLI plugin binaries). From the [ProgramData]
documentation:

> ProgramData specifies the path to the program-data folder (normally C:\ProgramData).
> Unlike the Program Files folder, this folder can be used by applications to store
> data for standard users, because it does not require elevated permissions.

It also mentions "It can’t contain any serviceable components.", effectively
meaning that these paths should not contain data that is managed (through
updates etc.), making it a poor choice for installing "system wide" CLI plugins.

This patch removes the path from the list, given that this location is no longer
used by Docker Desktop, and the CLI-plugin API is considered an internal
implementation (since 459c6082f8).

Sebastiaan van Stijn 7b624841c4 update minimum go version to go1.24
Various dependencies, including "golang.org/x/.."  started to update
the minimum required version,so we should follow suit for the next
release.

Note that the `//go:build` directives not necesserily have to be
updated, but it's good to keep them in sync until we have a go.mod

Sebastiaan van Stijn ec912e5524 cli-plugins/manager: allow schema-versions <= 2.0.0
The CLI currently hard-codes the schema-version for CLI plugins to
"0.1.0", which doesn't allow us to expand the schema for plugins.

As there's many plugins that we shipped already, we can't break
compatibility until we reach 2.0.0, but we can expand the schema
with non-breaking changes.

This patch makes the validation more permissive to allow new schema
versions <= 2.0.0. Note that existing CLIs will still invalidate
such versions, so we cannot update the version until such CLIs are
no longer expected to be used, but this patch lays the ground-work
to open that option.

Sebastiaan van Stijn 9b2f831452 cli-plugins/manager: ignore broken symlinks
Before this patch, a broken symlink would print a warning;

    docker info > /dev/null
    WARNING: Plugin "/Users/thajeztah/.docker/cli-plugins/docker-feedback" is not valid: failed to fetch metadata: fork/exec /Users/thajeztah/.docker/cli-plugins/docker-feedback: no such file or directory

After this patch, such symlinks are ignored:

    docker info > /dev/null

With debug enabled, we don't ignore the faulty plugin, which will
make the warning shown on docker info;

    mkdir -p ~/.docker/cli-plugins
    ln -s nosuchplugin ~/.docker/cli-plugins/docker-brokenplugin
    docker --debug info
    Client:
     Version:    29.0.0-dev
     Context:    default

    # ...

We should als consider passing a "seen" map to de-duplicate entries.
Entries can be either a direct symlink or in a symlinked path (for
which we can filepath.EvalSymlinks). We need to benchmark the overhead
of resolving the symlink vs possibly calling the plugin (to get their
metadata) further down the line.

Sebastiaan van Stijn 2351f5b915 cli-plugins/manager: replace pluginNameRe for isValidPluginName utility

if the name consisted of lowercase alphanumeric characters. Replace it

Sebastiaan van Stijn 549d39a89f cli-plugins/manager: fix Plugin marshaling with regular errors
Go does not by default marshal `error` type fields to JSON. The manager
package therefore implemented a `pluginError` type that implements
[encoding.TextMarshaler]. However, the field was marked as a regular
`error`, which made it brittle; assining any other type of error would
result in the error being discarded in the marshaled JSON (as used in
`docker info` output), resulting in the error being marshaled as `{}`.

This patch adds a custom `MarshalJSON()` on the `Plugin` type itself
so that any error is rendered. It checks if the error used already
implements [encoding.TextMarshaler], otherwise wraps the error in
a `pluginError`.

Sebastiaan van Stijn 091421f13f cli-plugins/manager: getPluginDirs: remove redundant error-return
This function returned an error (if any) from [config.Path]. However, the
only situation in which an error could be returned was if the given path
to append to `config.Dir` was outside of the config directory. This can
only happen if the path to append would try to traverse directories (e.g.,
passing `../../cli-plugins`).

Given that we're passing a hard-coded value, that would not be the case,
so we can simplify the code to join the path directly, and don't have to
handle errors.
