code-review

Structured PR review — security scan, correctness, consistency, style. Covers diff analysis, comment posting via gh, and priority-based finding reports. Use when: A PR needs review, someone asks for code feedback, or changes need security/correctness validation before merge. Also use for pre-commit review of your own changes. Don't use when: The issue is a runtime pod failure (use pod-troubleshooting), a Flux reconciliation error (use flux-debugging), or a CI build failure (use ci-diagnosis). Don't use for architecture-level design discussions (use architecture-design instead). Outputs: Review comment posted on the PR via `gh pr review`, or a structured findings report grouped by severity (Critical/High/Medium/Low).
