feat(sidebar): worktree indicator on session rows

[TheIcarusWings]

Sessions running in a git worktree now show a small FolderGit2 icon in the sidebar row, next to the terminal-status icon, with a tooltip giving the worktree folder and branch. This makes worktree sessions distinguishable from main-checkout sessions at a glance.

Detection uses the existing thread.worktreePath, no extra git calls. The indicator sits in the row's right-side cluster rather than inside the timestamp/meta span, because that span is pointer-events-none and fades on row hover, which makes tooltips there unreachable.

Tooltip on hover:

Verified in a live session with real worktree threads (screenshots above). vp check and typecheck pass.

Note

Low Risk
Small, read-only UI change driven by existing thread metadata; no new git calls or backend behavior.

Overview
Sidebar session rows now show a worktree indicator when thread.worktreePath is set, so worktree sessions are visually distinct from main-checkout sessions.

A new ThreadWorktreeIndicator renders a FolderGit2 icon with a tooltip (formatted folder via formatWorktreePathForDisplay, plus branch when present) and an accessible aria-label. It is placed in the row’s right-side icon cluster in SidebarThreadRow—alongside preview port and terminal status—rather than in the timestamp/meta area that uses pointer-events-none and fades on hover.

Coverage is added in ThreadStatusIndicators.test.tsx for the accessible label and for hiding the indicator when the worktree path is missing or whitespace-only.

Note

Add worktree indicator icon to sidebar session rows

Adds a new ThreadWorktreeIndicator component in ThreadStatusIndicators.tsx that renders a FolderGit2Icon with an accessible tooltip showing the formatted worktree path and branch. The indicator is inserted into the thread row actions area in Sidebar.tsx and renders nothing when worktreePath is absent or whitespace.

Cached bundle skips symlink fix

Medium Severity

buildMacLauncher now copies with verbatimSymlinks, but when an existing .electron-runtime bundle matches metadata.json, it returns that copy without rebuilding. Upgrades from a broken staged bundle keep the old absolute symlinks, so pnpm start:desktop on macOS can still hit ICU/GPU helper crashes until .electron-runtime is deleted manually.

This finding refers to the launcher change, which has been split out of this PR into #3058. It is addressed there: LAUNCHER_VERSION is bumped so previously staged bundles with rewritten symlinks are invalidated and re-copied instead of being reused by the metadata check. This PR is now sidebar-only.

Approvability

Verdict: Approved

Simple UI addition that displays a worktree indicator icon on sidebar session rows. The component is purely presentational with no business logic changes, and includes test coverage. The unresolved review comment references a file not modified by this PR.
