Review round 1 follow-ups:
- Reference the built-in $GITHUB_SHA env var in run scripts instead of
interpolating ${{ github.sha }}, removing the GitHub Actions script-injection
surface (SonarCloud security rating on new code).
- Add a concurrency group (cancel-in-progress: false) to
pact-record-deployment.yml so back-to-back tag pushes don't race the recording.
- Add timeout-minutes: 5 to guard against a hung tailnet join.
