feat(web): add the web adapter with the shell, home, summary and refs pages

Components per mockup D (topbar, statusbar, footer with the AGPL source
link, facts, clone, home row, outline, readme, keys, overlays), embedded
content-hashed assets, goldmark Markdown with a link and image policy,
and 404/500/empty state pages. The adapter only depends on the ermite-api
Connect clients.

26+// a page: raw HTML is dropped, and links and images follow the policy below.
27+//
28+// Link policy:
29+// - http and https links are kept, with rel="nofollow noopener noreferrer";
30+// - relative links and links to the root of the repository are rewritten to
31+// the blob route of the ref being viewed, never above the repository root;
32+// - #fragments point at the (prefixed) heading ids;
33+// - everything else (javascript:, data:, vbscript:, file:, mailto:,
34+// protocol-relative //host, empty targets…) loses its link: the text stays;
35+// - images are never loaded (the CSP forbids other origins, and the design
36+// shows an image as its alt text): each becomes <span class="alt">[alt]</span>.
