Subject: [PATCH] Race a direct CORS fetch alongside Jina in cliche highlighter
 URL loading

Fire both requests in parallel when loading a URL. Prefer the Jina
Reader result; if Jina fails (HTTP error or network), quietly fall back
to the direct fetch in case the site serves open CORS headers. If both
fail, show the original Jina error.
