refactor: reset message IDs on new turn and add activity log handlers

- Reset assistant message and thought IDs when starting new agent turn
- Add comprehensive activity log handlers in session context
- Handle tool calls, results, and errors with proper state updates
- Add transcription and assistant chunk streaming handlers
- Improve audio playback with proper error handling and confirmation
- Use generateMessageId() for consistent ID generation
- Filter out transcription activity logs from chat
- Stop audio playback when real speech is detected
