refactor(cli): Add subcommands for wake and sleep operations

- Restructure CLI to use subparsers for wake and sleep commands
- Add separate argument parsers for wake (port 9) and sleep (port 9999) commands
- Maintain backward compatibility with existing authentication and configuration
- Update help text and examples to reflect new command structure
