Validate hreflang tags and check every return link.

Checks a page's hreflang annotations against Google's documented rules: HTML link tags and HTTP Link headers, ISO 639-1 language and ISO 3166-1 region codes, x-default, self-reference and canonical mismatches. It also fetches up to 10 alternates to verify each one links back, because Google ignores a declaration without a return link. An offline validate endpoint covers staging HTML. Returns a score, grade and issues with stable codes.
