grid/detail views, TMDB TV search endpoint, and panel tab integration.
Includes film_ext-to-TV-series conversion for backward compatibility
and AI prompt instructions for [[tv_ext:...]] tags.

Wire up ContentPanel with tab navigation for all existing content types
(films, songs, podcasts, news, websites, magazine). Add complete Books
pipeline: type definition, extraction (tags + pattern matching), cover
fetching from Open Library, BookCard/BookGrid/BookDetail components,
inline chat cards, and prompt index badges.

Add a toggle in the chat header to collapse messages into a compact
prompt index showing user queries with content-type badges. Clicking
a prompt surfaces the corresponding content panel. Also fixes magazine
section extraction (### headers, emoji stripping, author regex) and
improves tile layout with editorial rhythm.
