Module sync 

Yjs Sync Protocol Implementation

This module implements the y-websocket sync protocol for compatibility with Hocuspocus/y-websocket clients. The protocol flow is:

1. Client connects and sends SyncStep1(client_state_vector)
2. Server responds with SyncStep2(server_diff) + SyncStep1(server_state_vector)
3. Client sends SyncStep2(client_diff)
4. Ongoing: Both sides exchange Update messages

Note: Awareness protocol (for cursors/presence) is handled by forwarding messages between clients without server-side state.
