exam-zh

Prepare and publish a formal exam-zh release: version metadata, CHANGELOG, l3build checks, build.py packages, release commit, tag, GitHub/Gitee push, GitHub Release assets, and Gitee Release assets. Use for 发版, 发布新版本, release, tag, or version bump requests.

Stage, commit, amend, and optionally push current exam-zh changes with scripts/git-update.sh. Use for ordinary commit/sync requests. Use examzh-release for releases, version bumps, tags, CTAN packages, GitHub Releases, and Gitee Releases.
