review-shell-change

Review a diff, branch, or PR in the MariaDB Shell repository. Runs the standard code review, then applies this repo's policy — what the other CI jobs already cover (so the review stays silent about it), the C/C++ defect classes worth hunting here, and the MariaDB-port conventions needed to judge a guard, a vendor difference, or a gated test correctly. Use this for any review request in this repository, in place of the built-in /code-review.
