Subject: [PATCH] ci: add concurrency-cancellation group to CI workflow

Superseded CI runs (rapid pushes to the same ref or PR) currently run to
completion, wasting Actions minutes. Add a concurrency group keyed on the
workflow name plus head_ref/ref so a newer run cancels the prior in-progress
one.
