refactor: restructure CLI with cobra command framework

- Replace flat flags with organized command structure
- Add commands: sync, list, manage, release, showcase, test
- Implement subcommands for better organization:
  - sync: repo, all, codeberg-to-github, github-to-codeberg, bidirectional
  - list: orgs, repos
  - manage: delete-repo, clean, batch-run
  - release: check, create (with --ai-notes support)
  - showcase: with --force, --output, --format, --exclude
  - test: github-token, codeberg-token, config
- Add comprehensive help with examples for all commands
- Fix config loading bug when path is empty
- Update README.md with new command structure and examples
- Maintain backward compatibility (old flags still work with warnings)

The new structure provides better discoverability, consistent naming,
and logical grouping of related functionality.
