* This PR optimizes socket delta event broadcasting by leveraging rooms. Instead of iterating through a user's sessions and emitting events individually, this change sends a single event to a user-specific room. This approach is more efficient, reducing overhead and improving performance, particularly for users with multiple concurrent sessions.
In testing this dramatically reduces emits and server load.
* Update main.py
Added userroom join
