Gh Pr Review

Overview

Generate an owner-grade PR review. The review must be strict regarding correctness and safety while maintaining a gentle tone with contributors, and it must be scoped to the PR's diff. Produce review-<pr>.md, which includes a Chinese narrative and English comment snippets ready for pasting into GitHub.

Hard Gates
