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.

+## Phase 2 — art and order (done)
 
-- **Art slots** instead of one backdrop: poster (2:3), fanart (16:9), banner
-  (ultra-wide), logo. The hero and the 16:9 tiles take fanart; the banner only
-  ever fills an ultra-wide strip.
-- **A larger size class for the hero.** `THUMBNAIL_MAX_EDGE` is 640 for every
-  picture; the hero is drawn up to ~1600 px wide.
-- **A poster grid on desktop**, as an option or the default — AniList's covers
-  are the best art this library has, and Android already proves the layout.
-- **More of the AniList answer kept**: format, season and year, studios,
-  director, tags, popularity, status, next airing episode — all in the search
-  response already, so no extra request.
-- **Sorts**: by the displayed name (English / romaji / folder, as a setting),
-  release season, rating, popularity, recently added (needs a `first_seen`
-  column), in-progress first.
-- **Franchise grouping** from relations: the Evangelion TV series, its two films
-  and the Rebuild folder; Made in Abyss and its three films; Mushishi and its
-  specials; the Heaven's Feel trilogy. One tile each, with the parts in release
-  order on the title page.
-- **Shelves**: genre, studio, director — this library has a Satoshi Kon shelf
-  waiting in it — format, decade, airing now.
+**More of the answer kept.** The AniList query now also asks for the full
+start date, broadcast season, banner, popularity, status, the next airing
+episode, spoiler-free tags ranked 60 or more, main studios, the `Director`
+among the most relevant staff, and the relations that keep to one story
+(`PREQUEL`, `SEQUEL`, `PARENT`, `SIDE_STORY`, `SUMMARY`, `ALTERNATIVE`,
+`COMPILATION`, `CONTAINS` — not `SPIN_OFF`, `CHARACTER` or `OTHER`, which reach
+into other franchises). All of it lives in `TitleDetails`, stored as one JSON
+column (**schema v10**). A match stored before that is fetched again *by id*
+(`Work::Refresh`) — never searched for, so hand-picked matches stay — and a
+refresh of the same entry keeps its episodes, fanart and enrichment record.
+Enrichment also stores the chain of entries it walked.
+
+**Art.** Three textures per title where there was one: the tile's (`Art::of`),
+the 2:3 cover (`Art::poster`), and wide art (`Art::wide` — fanart, else the
+AniList banner) decoded at up to 1920 px for the library's hero and the title
+page's band. The banner, wrong in a 16:9 tile, fits those strips as drawn.
+
+**Poster grid.** Settings → Appearance → *Library tiles*: covers (the default)
+or 16:9 stills. Covers fill their tile; a cover in a still-shaped tile is still
+fitted whole.
+
+**Names.** Settings → Appearance → *Title names*: the share's, English or
+romaji. Search matches all of them whichever is shown.
+
+**Sorts.** A–Z by the shown name, recently watched, recently added (from
+`node_first_seen`, which survives recrawls; files present before v10 count as
+added at 0), newest by air date, highest rated, most popular.
+
+**Franchises.** `pstr_core::franchise::group` joins titles that share a
+provider id — their own, a related one, or one their episode walk passed
+through. The grid folds each franchise into its lead (the first series to air,
+else the first film) with a `+N` badge; the stack button beside the sort turns
+that off. The title page shows the whole franchise in release order. On the
+library this was built against: Evangelion ×4, Made in Abyss ×4, Heaven's Feel
+×3, Mushishi with its OVA, Jujutsu Kaisen with *0*, Chainsaw Man with *Reze*.
+
+**Shelves.** `pstr_core::shelves::pick`: airing now, then directors, studios
+and genres, each only when it spans three *franchises* — Made in Abyss's four
+titles are one director's, and that is not a shelf — and a genre only under 40%
+of the library. Four at most, over the unfiltered library. Here: *Directed by
+Satoshi Kon*, *From MADHOUSE*, *From MAPPA*, *From Production I.G*.
+
+**The title page** adds the season, studios, director and next airing episode
+to its line of facts, and the tags beside the genres.
+
+Not done: Android shows none of this yet beyond what it already drew — the
+bridge carries `TitleDetails` through a hand-picked match, and the grouping,
+shelves and sorts are in `pstr-core` ready for it, but its screens are
+unchanged. TMDB fills no details.
