For a final version the publish job now pushes branch release/qqq-<version>
to QRun-IO/homebrew-tap and QRun-IO/scoop-bucket with PACKAGES_TOKEN and
opens a pull request "qqq <version>" in each; a human merges. A prerelease,
or a refused push or pull request, attaches qqq.rb / qqq.json to the release
as before, and never fails the release. The logic moves to
scripts/publish-packaging.sh, with a DRY_RUN=1 path that clones and commits
locally but writes nothing remote.
