Subject: [PATCH] fix(ci): add concurrency group to cancel superseded runs on
 force-push
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Force-pushes triggered a new pull_request synchronize event while the
previous run's lightweight jobs (conventional-commits, IPR) still held
the free-tier runner slots. The 4-runner Test Python matrix for the new
SHA was queued but never scheduled — the fast jobs always won. Required
a manual close/reopen to retrigger.

The concurrency block cancels in-progress runs for the same ref so the
new SHA's matrix jobs get scheduled immediately.

Closes #413
