Luca Rossi 98f0e68e38 feat: back/forward navigation between opened notes (#75) ...

* feat: add useNavigationHistory hook for browser-style back/forward

Pure state management hook that tracks a navigation stack of note paths
with cursor-based back/forward traversal. Handles edge cases: duplicate
pushes (no-op), forward stack cleared on new push, invalid path skipping,
and path removal when tabs close.

* feat: integrate back/forward navigation into UI and keyboard shortcuts

- Add Back/Forward arrow buttons to TabBar (left of tabs)
- Wire useNavigationHistory through App → Editor → TabBar
- Add Cmd+[ and Cmd+] keyboard shortcuts via useAppKeyboard
- Register Go Back/Go Forward in command palette
- History tracks active tab changes, skips closed tabs gracefully
- Navigation from history doesn't re-push to stack (ref guard)

* feat: add mouse button 3/4 and trackpad swipe for back/forward

- Mouse buttons 3 (back) and 4 (forward) trigger navigation
- macOS trackpad two-finger horizontal swipe triggers back/forward
  using accumulated wheel deltaX with a 120px threshold
- Debounced reset after 300ms of inactivity

* design: add back-forward-nav.pen with 3 state frames

Shows: default (both disabled), one note visited (back disabled),
two notes visited (back enabled). Matches tab bar button placement.
