Gitar Rules

➖ Flaky Test Retry: No CI failures detected. Some checks are in progress (Ruby, build) but no failures to retry.

➖ PR Summary Enhancement: PR already has comprehensive Gitar summary. New commit added minor documentation enhancements (intro paragraph, links) which don't require summary update as existing summary accurately covers the overall changes.
