feat: buffer/latency control + non-selectable node text

Browse Source 
Buffer Control:
- GET /api/quantum - reads current graph quantum via pw-metadata
- POST /api/quantum {quantum:N} - sets quantum via pw-metadata
- Toolbar dropdown with presets: 32, 64, 128, 256, 512, 1024, 2048, 4096
- Loads current quantum on startup

Text Selection Fix:
- Added user-select: none to wrap and canvas CSS
- Node text no longer gets selected when dragging
