RSS/Atom feed discovery API

Fetches a page, scans link rel=alternate tags plus common feed paths to locate RSS/Atom/JSON feeds, then parses the first discovered feed to preview its latest items. The value-add: one call goes from a bare site URL to discovered feed URLs PLUS a parsed preview of recent items. Answers 'find the RSS feed for this site', 'does this blog have a feed', 'discover Atom feeds on this page', 'get the feed URL and latest posts'.
