GRM-21: Implement commit validation, CI/CD workflows and repo automation

- Add scripts/validate_commit_msg.py with conventional commit enforcement
- Add scripts/configure_repo.py for Gitea branch protection and labels
- Add scripts/__init__.py for Python package importability
- Create Gitea Actions workflows: ci, auto-merge, post-merge, publish
- Update .pre-commit-config.yaml with commit-msg hook
- Update pyproject.toml pythonpath and coverage for scripts
- Add comprehensive unit tests for both scripts with 100% coverage
