* wip in the design doc
* fix: use Ctrl+Shift+J for worktree palette on non-darwin platforms
To avoid colliding with Ctrl+J (Line Feed) on Windows/Linux, we now
use Ctrl+Shift+J for the worktree jump palette on those platforms,
leaving Cmd+J for macOS.
* refactor: migrate QuickOpen to cmdk and unify overlay state
- Migrated `QuickOpen.tsx` to use `cmdk` (`CommandDialog`) for visual and
behavioral consistency with the new worktree jump palette, while keeping
the existing custom fuzzy match algorithm.
- Unified the overlay state systems (`activeModal`, `quickOpenVisible`,
`worktreePaletteVisible`) into a single `activeModal` union type.
- This automatically handles mutual exclusion without boilerplate
toggle logic spread across components.
* fix: forward QuickOpen and worktree shortcuts from browser guests
Added main-process interceptors for `Cmd/Ctrl+P` and `Cmd/Ctrl+1-9`
so that QuickOpen and numeric worktree jumping continue to work
even when an embedded browser guest (webview) has keyboard focus.
* fix: address review findings
- Set spawnEnv.SHELL before pty.spawn() in the fallback loop so the
child process inherits the correct SHELL value instead of the stale
original.
- Remove dead Cmd+P and Cmd+1-9 renderer keydown handlers from App.tsx;
these are now handled via IPC from createMainWindow.ts before-input-event
(the IPC handlers in useIpcEvents.ts have the same view-state guards).
