chore: bump version to 1.2.1

- Update version from 1.2.0 to 1.2.1 in __version__.py
- Enhance _get_process_resources() to return process running status as third value
- Add process.is_running() check to detect terminated processes accurately
- Refactor process resource monitoring logic to use running status flag instead of checking if cpu/mem > 0
- Simplify PMHQ and LLBot running state detection by using returned is_running value
- Improve reliability of process status detection for manager, PMHQ, and LLBot processes
