Universal PR review workflow for any AI assistant to verify architecture, clean code, SOLID design, and test quality in any programming language. Two modes: simple (default) reviews the diff with severity-ranked findings; advanced adds existing-comment dedup (never repeat what reviewers already said — agree/reply/react instead), security/performance/dependency review, and optional build+test verification in a temporary worktree. Use when asked to "review PR 123", "review this MR", "review this branch against develop", "compare and review feature/x", or "do a deep/advanced/thorough review of this PR".
