perf(starter): send font preloads as a Link header for Early Hints - #56

Conversation
Pages now send their type pairing's font preloads as a `Link` response header as well as `<link rel=preload>` in the head. On a Cloudflare zone with Early Hints on, the edge answers with a 103 carrying those links before the page, so the fonts start loading while the Worker renders.

Step 5 of the font work after #54. Pages send their type pairing's font preloads as a
Linkresponse header (rel=preload; as=font; type="font/woff2"; crossorigin), as well as the<link rel=preload>already in<head>. With Early Hints on for the zone, Cloudflare caches these links and answers later requests with a 103 before the page, so the fonts start loading while the Worker renders. Thesystempairing sends nothing.Checked: dev server responds with the header for a web-font pairing; CLI suite 165/165.
