Copilot code review expands: bot-authored and large PRs now covered, resolution reasons
GitHub Copilot code review now covers two PR types it previously couldn't: bot-authored PRs (including Copilot's own cloud agent) and large PRs, with the old 300-file / 20,000-line limit removed. Reviewers resolving a comment can now record a reason — Addressed, Won't fix, or Incorrect — giving the agent better signal on what to fix.
