Link repo header and add a "View original" link

The owner/name header in the layout now links to the owner page and the
repository root. tryRender passes the request's path and query through
as githubUrl — our URLs mirror GitHub's, so the same path is the page we
scraped — and the footer links there with rel="noreferrer", matching the
no-referrer policy used on redirects to github.com.
