Add bidirectional file sync, OT system, comments, and real-time collaboration

Implement full Overleaf integration with Socket.IO v0.9 real-time sync:
- FileSyncBridge for bidirectional temp dir ↔ Overleaf sync via chokidar + diff-match-patch
- OT state machine, transform functions, and CM6 adapter for collaborative editing
- Comment system with highlights, tooltips, and review panel
- Project list, file tree management, and socket-based compilation
- 3-layer loop prevention (write guards, content equality, debounce)
