feat(repos): support owner-based repository listing with robust lookup (#931)

- Add an owner flag to the repos list command to list repositories for a specific user or organization
- Implement owner-based repository listing by detecting whether the owner is an organization or a user and calling the appropriate API
- Improve error handling for owner lookup by checking HTTP status codes instead of relying on error string matching
- Align repository search logic with the updated owner lookup behavior using HTTP response validation
