Merge scripts/dev-instances into scripts/dev. Each branch gets its own
Compose project, container, volumes, port block, libvirt network, and
KVM VMs, so stop and start reuse the same data and worktrees do not
collide.
- Name instances after the branch; keep slots and APP_KEYs in the main
checkout's .dev-instances/ so they survive worktree removal
- Reuse existing QEMU VMs instead of recreating them; add dev:qemu --fresh
- Give each instance an isolated libvirt network (10.221.<slot>.0/24)
and VM names coolify-dev-<branch>--<profile>
- Publish per-instance browser ports and publish them with tailscale
serve when APP_URL is a tailnet host
- Add urls, exec, logs, container, destroy, and teardown commands; run
teardown from jean.json before Jean deletes a worktree
- Fix Reverb/terminal browser ports and the testing-host alias in the
instance compose file
- Keep fresh worktree instances working: pre-create laravel.log, log the
host dev:qemu call to stderr, and stop Vite from watching vendor/
