Review a pull request using the Review Horde — parallel specialist zombie agents. Use when the user says "review", "re-review", or "mirror" followed by a PR number (e.g. "mirror 1641", "re-review 1234"). "mirror" = self-review before teammates see it; "re-review" = check if prior issues were fixed; default = full review that posts to GitHub. Also use when the user says things like "look at PR 1234", "can you review this", "check if the issues on PR are resolved", "follow up on PR", or drops a bare number that looks like a PR.
