feat: add --delete-repo command to delete repositories from all organizations

- Added --delete-repo flag that accepts a repository name
- Implemented DeleteRepo() methods in both GitHub and Codeberg API clients
- Created HandleDeleteRepo handler with interactive confirmation
- Shows clear status of repository across all configured organizations
- Requires user to type "yes" to confirm deletion
- Provides detailed feedback on success/failure for each deletion
- Updated documentation and usage help
