name: Version bump & release

# Manual trigger — click "Run workflow" in the Actions tab, choose
# patch / minor / major. The workflow computes the next semver,
# updates package.json, mobile/package.json, and the Android
# build.gradle, commits the change, tags it, and pushes — which
# triggers the android-release and docker-publish workflows.
