Improve CLI command inline pane and monitoring behavior

- Track user-initiated expansion state to avoid auto-collapse conflicts
- Invert inline action visibility so terminal block hides while inline pane owns the expanded body
- Add scrollable output rendering in requested command expanded view
- Simplify CLI monitor nudge message and extract to reusable method
- Show only latest user query and assistant text in monitor task transcript
- Add handle_ctrl_c_for_conversation to status bar for child agent cancellation
- Update rig_request tests for adjusted monitor nudge wording
