fix: editor improvements — isDir bug, scroll-to-line, Quick Open, a11y

- Fix isDir heuristic: use backend-provided isDirectory instead of
  filename-based guessing (breaks for Makefile, .github, etc.)
- Add scroll-to-line on search result click via editorPendingGoToLine
- Add Cmd+Shift+W shortcut for toggling line wrap
- Rewrite Quick Open to fetch all project files from backend API
  instead of flattening the loaded tree (limited to expanded dirs)
- Fix fd leak in atomicWrite: close file handle in finally block
- Add a11y: role=dialog/alert, aria-modal, aria-label on modals
- Add type=button on error state buttons
