feat: implement presentation mode for touch table displays

Add comprehensive presentation/viewer mode optimized for touch table
interactions with clean UI and touch-friendly timeline navigation.

State Management:
- Add presentationMode toggle to settingsStore with localStorage persistence
- Add preferPresentationMode to DocumentMetadata for per-document preferences
- Auto-enter presentation mode when opening documents that prefer it
- Add setDocumentPresentationPreference() helper to workspaceStore

UI Components:
- Create PresentationTimelineOverlay component with floating timeline control
  - Previous/Next navigation buttons with chevron icons
  - Horizontal scrollable state list
  - Only shows when document has 2+ states
  - Proper vertical alignment using flex items-stretch and centered content
  - Scales to ~10 states with max-w-screen-md (768px) container
- Create presentation.css for touch optimizations (60px+ touch targets)

UI Modifications:
- App.tsx: Conditional rendering hides editing chrome in presentation mode
- GraphEditor: Disable editing interactions, keep pan/zoom enabled
- MenuBar: Add "Presentation Mode" menu item
- Global shortcuts: F11 to toggle, Escape to exit presentation mode

Tests:
- Add presentation mode tests to settingsStore.test.ts
- Add document preference tests to workspaceStore.test.ts
- All 376 tests passing
