before: gitrepo vs git packages after: git package fully handle all git operations by the way, use `WithRepo(repo)` instead of `WithDir(repo.Path)` to hide path details. benefits: 1. remove all unnecessary wrappers, developers no need to struggle with "which package should be used" 2. simplify code, RepositoryFacade can (will) be used everywhere, all "path" details are (will be) hidden
