feat(cron): add distinct Cron message type and exit summary

- Introduce SendMessageType.Cron to differentiate cron-triggered prompts
  from user queries
- Skip UserPromptSubmit hook for cron messages
- Add getExitSummary() to display active loops when session ends
- Add tests for exit summary functionality

This improves cron loop handling by treating scheduled prompts
differently from user-initiated queries and provides better UX
when sessions end with active loops running.
