fix: improve ci-health-check signal and replace node with jq

- Replace node -e JSON parsing with jq (available on our runners)
- Exclude Release workflow failures from FAIL count — these fail at
  the post-release PR-creation step due to missing RELEASE_APP org
  secrets (tracked in PRI-380), not actual CI breakage
- Demote Release failures to WARN so the health check exits 0 when
  only Release is broken, giving clean signal for real CI problems
- Increase run limit from 5 to 10 for better intermittent failure detection
- Remove unnecessary Node.js setup step from the workflow
