Asynchronous WordPress Link Scanner

I need a compact, production-ready WordPress plugin that scans posts, pages, and any registered custom post type for broken internal links only. The checker must hit the usual HTTP status codes—200, 301, 404, 500—and flag redirects while making sure the same URL is never tested twice...
