<!-- This is an auto-generated comment: release notes by coderabbit.ai
-->
## Summary by CodeRabbit

- **Documentation**
	- Enhanced CLI help text by adding and refining command descriptions:
		• Logs command now clearly displays “View logs.”
		• Restart command now focuses solely on restarting the API.
		• Start command now shows “Start the Unraid API.”
		• Stop command now explicitly states its stopping action.
• Environment switch command now indicates its role in switching the API
environment.
