dev-inf: Add feedback labels to AI review comments

When the AI review detects potential bugs, the comment now includes
instructions for reviewers to tag the PR based on whether the finding
was helpful:
- O-AI-Review-Real-Issue-Found: Issue was real or helpful
- O-AI-Review-Not-Helpful: Issue was not helpful

This feedback will help improve the AI review system by tracking
the accuracy and usefulness of detected issues.
