- Convert `get_recent_group_speaker` and `count_messages_between` in `chat/utils` to async functions to align with underlying asynchronous database calls, preventing potential blocking issues.
- Implement optional import for `sleep_system` within the `affinity_flow_chatter` plugin using a try-except block. This decouples the hard dependency between the two plugins, enhancing modularity and ensuring the chatter plugin remains operational even if the sleep system is unavailable.
