#7487: docs: add code review for recent security commits (b796f6e..411d5fd)

https://claude.ai/code/session_01UkeAKoGgrrYkBwrH1Yveks <!-- greptile_comment --> <h2>Greptile Overview</h2> <h3>Greptile Summary</h3> This PR adds `CODE_REVIEW.md`, a repo-persistent writeup reviewing five recent security/maintenance commits (b796f6e..411d5fd), summarizing intent, positives, and potential follow-ups per commit. Since this is documentation (not code changes), the main review focus is on long-term usefulness and clarity for future readers browsing the repo history. <h3>Confidence Score: 4/5</h3> - This PR is safe to merge; it adds documentation only. - Changes are limited to adding a new markdown file and do not affect runtime behavior. Remaining concerns are about doc longevity/clarity (stale metadata, language accessibility), not correctness or security. - CODE_REVIEW.md <!-- greptile_other_comments_section --> _{(2/5) Greptile learns from your feedback when you react with thumbs up/down!} <!-- /greptile_comment -->
