Generate CLI reference for evalprotocol.io (#375)

* save

* update

* Enhance CLI documentation generation by updating subparser help extraction. Introduce a method to hide suppressed commands from help output and ensure accurate help text is included for subparsers.

* remove generated cli-reference

* update
