The workflow runs on the runner's host and builds in the project's Docker
image through scripts/ci.sh, as on a developer's machine. A tag v*, or a
run by hand for an older tag, builds that tag's sources, signs the Update
File with the key held in the repository's secrets, checks the signature
against the public key in the sources, and publishes a Gitea release with
the .ota, the factory image, the ELF and checksums.
