Add build-check job to decouple the required status check name

The "Build" status check required by branch protection should stay
named "Build" regardless of how the build job's own shape changes
(e.g. if it's later wrapped in a reusable workflow, which changes the
reported check name). This trivial gate job guarantees something
always reports under the literal name "Build" when the real build
fails or is cancelled.
