template-downstream

Update .claude/, .mcp.json, and .pre-commit-config.yaml from the upstream python-project-template repository into the current project. Only files that exist upstream are updated — project-only files are never deleted. Use when pulling latest tooling, rules, hooks, or skills from the canonical template into this project. Triggers on: "템플릿 최신화", "template sync", "upstream 반영", "template 업데이트".
