Channel for DB Sync protocol messages.

Handles communication between sender and receiver sites during a data sync session.

Architecture

The SENDER site hosts this channel (has data to share). The RECEIVER connects via WebSocket to pull data.

Data Flow:

1. Receiver's WebSocketClient connects to this channel
2. Receiver sends requests (e.g., "request:tables")
3. Channel handles request by querying local database
4. Channel sends response back to Receiver
