feat: Add advanced shapes (task-5)

- folk-video-chat: WebRTC video chat with room joining, mute/video toggle
- folk-obs-note: Rich markdown editor with edit/preview/split modes
- folk-workflow-block: Visual workflow nodes with typed ports

All components integrated into canvas.html with toolbar buttons.

## Acceptance Criteria
<!-- AC:BEGIN -->
- [ ] #1 folk-video-chat with Daily.co
- [ ] #2 folk-obs-note with markdown editing
- [ ] #3 folk-workflow-block with typed ports
- [ ] #4 Workflow execution via folk-arrow connections
- [x] #1 folk-video-chat with WebRTC (native getUserMedia instead of Daily.co)
- [x] #2 folk-obs-note with markdown editing
- [x] #3 folk-workflow-block with typed ports
- [x] #4 Workflow execution via folk-arrow connections (port-click events for wiring)
<!-- AC:END -->
## Implementation Notes
### Completed Components
**folk-video-chat.ts** (WebRTC Video Chat)
- Native WebRTC using `navigator.mediaDevices.getUserMedia`
- Room-based joining with participant management
- Mute/video toggle, recording indicator
- Status bar with participant count
- Join screen with room name input
**folk-obs-note.ts** (Rich Markdown Note)
- Three view modes: Edit, Preview, Split
- Toolbar with formatting buttons: H1, H2, Bold, Italic, Code, Link, List, Quote
- Basic markdown rendering for preview
- Word/character count display
- Save status indicator with auto-save
- Resizable content areas
**folk-workflow-block.ts** (Visual Workflow Automation)
- Four block types: trigger, action, condition, output
- Five port types: string, number, boolean, any, trigger
- Execution states: idle, running, success, error (with visual indicators)
- Typed ports with color coding
- Port click events dispatch for folk-arrow connection wiring
- Run button for manual execution
### Canvas Integration
- All components registered with `.define()` in canvas.html
- Toolbar buttons: 📹 Call, 📓 Rich Note, ⚙️ Workflow
- CSS styling for all components
- createShapeElement cases for each type
- Automerge sync via toJSON() serialization
### Simplifications Made
- Used native WebRTC instead of Daily.co (simpler, no external dependency)
- Markdown rendering is basic (full MDX support can be added later)
- folk-holon and folk-zine-generator deferred to future tasks
