Full PR lifecycle management: list, analyze, validate, and merge pull requests. Auto-detects validation gates per package and integrates a code-review pass for code analysis. Use when: managing PRs, checking PR status, reviewing open PRs, merging PRs, triaging PRs, cleaning up stale PRs, validating PR readiness, or any PR maintenance task. Even if the user just says 'merge', 'PR status', 'open PRs', 'stale PRs', 'validate branch', 'triage', or references a PR number — this skill applies.
