android.yaml runs Gradle gates in the pinned Android image on android-build
(optional emulator tasks, optional publish to the Gitea Maven registry on
vX.Y.Z tags). windows.yaml and macos.yaml run the caller's commands directly
on the Windows / macOS host runners and attach artifacts plus SHA256SUMS to
the Gitea release on v* tags.
