feat: Add 4 FolkJS shape components (slide, chat, google-item, piano)

- folk-slide: Presentation slide container with dashed border
- folk-chat: Real-time chat with username persistence
- folk-google-item: Data card for Google services with visibility toggle
- folk-piano: Chrome Music Lab Shared Piano iframe embed

All components extend FolkShape, implement toJSON(), and support
drag via data-drag attribute. Toolbar buttons added for each.

## Notes
### Implementation Complete
Created 4 FolkJS web components:
1. **folk-slide.ts** (`lib/folk-slide.ts`)
- Simple slide container with dashed border
- Label display (e.g., "Slide 1")
- Minimal implementation for presentation mode
2. **folk-chat.ts** (`lib/folk-chat.ts`)
- Real-time chat with message list
- Username prompt with localStorage persistence
- Message input form with send button
- Orange header theme matching original
- Emits `message` events for sync integration
3. **folk-google-item.ts** (`lib/folk-google-item.ts`)
- Data card for Gmail/Drive/Photos/Calendar items
- Visibility toggle (local/shared)
- Service icons and relative date formatting
- Dark mode support
- Helper function `createGoogleItemProps()`
4. **folk-piano.ts** (`lib/folk-piano.ts`)
- Chrome Music Lab Shared Piano iframe embed
- Loading/error states with retry
- Minimize/expand toggle
- Sandboxed with audio/MIDI permissions
All components:
- Extend FolkShape base class
- Use CSS-in-JS via template literals
- Support drag from header/container via `data-drag`
- Implement `toJSON()` for Automerge sync
- Registered in `canvas.html` with toolbar buttons
