feat(core,meta,app,android,cli): sort, group and shelve the library

The AniList query now keeps the start date, season, banner, popularity,
status, next airing episode, tags, main studios, director and story
relations, as TitleDetails in one JSON column (schema v10). Matches
stored without them are fetched again by id, never searched, so
hand-picked matches stay; refreshing the same entry keeps its episodes
and fanart. Enrichment records the entries it walked. node_first_seen
remembers when each file appeared, across recrawls.

pstr_core::franchise groups titles that share a provider id. The grid
folds each franchise into its lead with a +N badge, and the title page
lists the whole franchise in release order. pstr_core::shelves picks
rows by airing status, director, studio and genre. A row needs three
franchises, so one franchise's titles never make a row on their own.

Desktop:
- Covers are the default grid (Settings > Appearance > Library tiles).
- The hero and title band use fanart or banner decoded at 1920 px.
- New sorts: recently added, newest, highest rated, most popular.
- Titles can show the share's, English or romaji name; search matches
  all of them.

Android carries TitleDetails through a hand-picked match; its screens
are unchanged.
