- Added RedisMessageBus for message distribution using Redis Pub/Sub. - Introduced LocalMessageBus as a no-op implementation for single-server mode. - Created messagebus interface for abstraction of message distribution. - Implemented awareness management methods: SetAwareness, GetAllAwareness, DeleteAwareness, and ClearAllAwareness. - Added logger utility for structured logging with zap. - Refactored SniffYjsClientIDs and MakeYjsDeleteMessage functions for improved readability.
