feat: implement background process logging and cleanup

Browse Source 
- Add persistent logging for backgrounded shell processes in ~/.gemini/tmp/background-processes
- Implement automatic cleanup of background logs older than 7 days on CLI startup
- Support real-time output syncing to log files for both PTY and child_process execution
- Update UI to indicate log file availability for background tasks
- Add comprehensive unit and integration tests for logging and cleanup logic
