fix: prevent gateway status from starting full gateway runtime

- Fix issue where 'picoclaw gateway status' would start a full gateway worker
- Add argument check in gateway command to delegate 'status' to status command
- Export StatusCmd() function to allow gateway package to call it
- Update gateway command to accept up to 1 argument for status subcommand

Fixes #671
