Prepare GitHub pull requests for review and follow up on PR review comments. Use before any PR creation or update, including "open a PR", "create a PR", "make a pull request", `gh pr create`, writing/updating a PR body, requesting review, handling Copilot or human review feedback, resolving comments, or asking whether a branch is ready to review. Includes rubber ducking, semantic commits, PR body/review guidance, 5-minute Copilot feedback follow-up scheduling, and work-repo vs personal-project boundaries.
