Module error 

Error types for each architectural layer.

Errors are split by layer so callers can match on the granularity they need:

• CodecError — JSON serialization / deserialization failures.
• ConnectError — WebSocket connection establishment failures.
• SendError / RecvError — frame-level I/O on an established connection.
• SessionError — high-level session lifecycle errors (setup, reconnect, etc.).
