- Add .github/workflows/close-prs.yml — politely auto-closes any opened/reopened pull request (pull_request_target, no PR-code checkout, so it's safe for fork PRs). - README: note up front that issues are disabled, PRs are auto-closed, no support/contributions, and that forking under GPL-3.0 is welcome.
