Vinta Chen 25a3f4d903 refactor(parser): remove resources parsing, preview, and content_html fields
parse_readme now returns list[ParsedGroup] instead of a tuple. The
resources section (Newsletters, Podcasts), preview string, and
content_html rendering are no longer produced by the parser or consumed
by the build. Removes _render_section_html, _group_by_h2, and the
associated dead code and tests.
