Subject: [PATCH] Add cancel-in-progress concurrency to reusable CI (#38)

Superseded CI runs on the same ref keep consuming runners and delay
feedback on the latest push. Add a job-level concurrency group keyed
on github.workflow and github.ref so a new push cancels the in-flight
CI run for that branch.

Concurrency is set at the job level rather than the workflow level
because these are workflow_call reusable workflows: workflow-level
concurrency would resolve github.workflow against the caller's context,
collapsing unrelated callers into one group. cd-* deploy workflows are
intentionally left untouched to avoid cancelling in-flight deploys.
