OPDS 2.0 feeds may list a publication in summary form (title, cover, and
only a rel="self" link of type application/opds-publication+json), serving
the full record (acquisition links, description, publisher, subjects) only
when the client follows that link on click, as Thorium does. Readest
ignored it, so such books showed no download option and no description.
Add opdsPublication.ts with getPublicationDetailHref and
parsePublicationDocument (OPDS 2.0 JSON and Atom entry, absolutizing
link/image hrefs), and dereference the link in the OPDS page when a
feed-selected summary advertises one, upgrading the detail view in place
once it loads.
Also render an OPDS 2.0 JSON HTML description as sanitized markup instead
of literal tags by falling back from the typed content to the plain
description string in getOPDSDescriptionHtml.
