feat: add real-time collaborative editing with Hocuspocus + Yjs

- Server: Hocuspocus server integrated via WebSocket upgrade on /_collab
- Server: Database extension for persistence
- Frontend: Yjs + HocuspocusProvider for real-time sync
- Frontend: @tiptap/extension-collaboration for Yjs-based CRDT editing
- Frontend: @tiptap/extension-collaboration-cursor for live cursors
- Editor: history disabled when collab active (Yjs handles undo/redo)
