actions/upload-artifact@v7 fails on Gitea Actions — the GitHub
artifact API has compatibility gaps the Gitea runtime layer does not
fully cover, and v7 specifically tripped exitcode 1 on the Strato
runner. The build itself runs fine; the artefact was never consumed
by anything (release.yml does its own latest.zip lookup), so the
cleanest fix is to make build.yml a pure compile-health check
without artefact upload.
