perf: stability and performance improvements with some minor UI issues resolved (#172)

* Stability and performance improvements. (#1)

## Changelog

### Performance Improvements

- **perf: make terminal creation cwd check async (#9)**  
  Replaced synchronous `fs.existsSync` with `fs.promises.access` in the terminal creation handler to prevent blocking the event loop.  
  Improves throughput under high load.

- **perf: optimize fuzzyMatchScore by avoiding redundant lowercasing (#8)**  
  Renamed `fuzzyMatchScore` to `fuzzyMatchScoreNormalized` and updated it to accept a pre-lowercased query, avoiding repeated string allocations.  
  Updated the call site in `searchFilesystemFiles`.  
  ~25% search performance improvement on large datasets.

- **perf: use async file read in update-install handler (#7)**  
  Replaced `fs.readFileSync` with `await fs.promises.readFile` to avoid blocking the event loop.  

  **Benchmark (10k ops):**
  - Sync: ~95ms (blocking)  
  - Async: ~1124ms (non-blocking)  

  Higher per-call overhead, but better server responsiveness.

- **perf(server): optimize mkdir endpoint with async fs (#6)**  
  Replaced `fs.mkdirSync` with `await fsPromises.mkdir` in `/api/fs/mkdir`.  
  Prevents event-loop blocking and improves concurrent performance.  

  **Result:** ~2× throughput improvement (100 concurrent requests).

- **perf: parallelize fs checks in validateProjectEntries (#4)**  
  Replaced serial `for...of` with `Promise.all + map`.  
  Reduced validation time for 500 projects from ~110ms to ~20ms (~5× speedup).

- **perf: cache getLoginShellPath result to avoid blocking event loop (#5)**  
  Cached `getLoginShellPath` result to avoid repeated `spawnSync` calls (~400ms each).  
  Subsequent calls reduced to <1ms.

### Server Fixes

- **fix(server): use async check for terminal restart endpoint (#3)**  
  Replaced `fs.existsSync` with `fs.promises.stat` in `/api/terminal/:sessionId/restart`.  
  Added directory validation for better robustness.

---

### UI & Accessibility

- **feat(ui): add aria-labels to git identities sidebar buttons (#1)**  
  - Added `aria-label="Create new profile"` to the create button  
  - Added `aria-label="Profile actions"` to the dropdown trigger  
  - Added `.Jules/palette.md` for UX/a11y learnings

### UI Performance (Bolt)

- ** Bolt: Optimize MessageList re-renders by preserving referential equality (#2)**
- ** Bolt: Optimize MessageList re-renders by preserving referential equality (#11)**
- ** Bolt: Optimize MessageList re-renders by preserving referential equality (#12)**

- Reduced horizontal gaps in mobile model controls.
- Added max-width constraints to model, variant, and agent labels on mobile to prevent overflow and cramping.
- Optimized spacing for mobile view.

* feat(git): auto-select gitmoji for generated commit messages

When the "Generate commit message" feature is used and gitmoji is enabled, automatically prepend the appropriate gitmoji based on the commit subject keywords.

- Added `KEYWORD_MAP` to map commit types to gitmojis.
- Added `matchGitmojiFromSubject` helper.
- Updated `handleGenerateCommitMessage` to apply the gitmoji.
