f30e58c 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.

Description

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.
