feat(src): add inhibit command to prevent system sleep

The new inhibit subcommand lets users block suspend/sleep while optionally running a command, specifying why and who, and running in daemon mode.

- New Features
  - Introduce Inhibit subcommand with command, why, who, and daemon options
- Enhancements
  - Extend CLI parsing to support additional arguments
  - Enable background inhibition via daemon flag for continuous prevention
