LIB.C1 Library collections: the Library is the one home of every object; each app starts from a default collection

Owner 2026-11-05: library as the primary source of all object information; CivilCraft gets a default collection from the Library (its plants and items), usable in every app. Spec docs/0.9-LIBRARY-COLLECTIONS.md. Built: collections tables (migration 124), LibraryCollections, GET /api/v1/library/collections[/<slug>|/app/<app>], bin/library-collection-make.php, test bin/test-library-collections.php (17/0). Next: publish the 421 seed plants (bin/library-import-plants.php, dry run clean), make civilcraft-landscape the CivilCraft default, then CivilCraft Landscape loads it (C.3), places any Library item (C.4), other apps add it (C.5). Parametric Library objects (params + generator) are a separate track. C.2 done 2026-11-05: 421 seed plants published as Library plant items (system author), collection civilcraft-landscape published and set as CivilCraft default; served at /api/v1/library/collections/app/civilcraft. C.3 started 2026-11-05 (in /lab): the Plants section says where its list came from (the civilcraft-landscape collection, count, revision, or the built-in list when the Library is unreachable); Landscape panel sections fold shut and a menu command opens the one it works with (landscape/fold.js). The app still reads plants.csv for the data; reading the collection manifest itself comes next. C.3 done 2026-11-05 (in /lab): CivilCraft Landscape now reads its plants from its default collection (GET /api/v1/library/collections/app/civilcraft/plants.csv; every published plant when no collection is set; the built-in list when the Library cannot be reached). Panel sections: opening one shuts the others unless locked (lock icon by the caret). Landscape tests 533/0, collections 17/0. C.4 (place any Library item) and C.5 (other apps) still planned.
