Subject: [PATCH] ci: supersede stale runs, serialize releases
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Checks now carry `concurrency` with cancel-in-progress so a newer push to
the same ref kills the queued predecessor instead of stacking runs on the
self-hosted pool. Release workflows get the same grouping with cancelling
disabled — a publish must never be interrupted halfway.
