Add GitHub repository creation and improve error handling

- Add --create-github-repos flag to automatically create missing GitHub repositories
- Implement GitHub API client with token support from config/env/file
- Add Codeberg API integration to sync all public repositories
- Make sync operations stop on first error for better debugging
- Support GitHub repo creation for all sync commands (--sync, --sync-all, --sync-codeberg-public)
- Add comprehensive error messages and debug logging
