 * One-shot diff. Two shapes:

 *                                (old.url) against the freshly fetched body
 *                                (new.markdown). Populate the cache first with
 *                                `wigolo fetch <url>` / `wigolo crawl`.
 *   diff --old=… --new=…       — inline text diff, no network.
