Research direction

Examine the existing 'registry' command implementation in the slimtoolkit/slim codebase, likely under the 'cmd' directory. Check the comments in issue #377 for any prior discussion or suggested approach. Look at how other sub commands are structured to understand patterns. The push sub command should handle authentication, image pushing, and registry interactions. No linked PR exists, so the implementation is open. A good starting point is to analyze the current registry command's code and interfaces.
