H001

No site.url: a build has no absolute canonical, og:url or og:image, and a server takes them from the request's Host header.

Fix: Set site.url, or WEFT_SITE_URL in the deploy environment.

Status in weft@0.1.0: reported by weft check and by weft routes --meta, per route, on what the routes produce.
