DeduplicationService colapsaba settings, tags y week plans pero NO los
platos, dejando duplicados de CloudKit (mismo UUID) que causaban el crash
de arranque y platos repetidos en pantalla. Se añade dedupeDishes:
- Solo agrupa y colapsa copias que comparten el mismo id (nunca fusiona
platos distintos ni toca platos únicos).
- Keeper elegido de forma DETERMINISTA (copia más rica: foto/desc/
ingredientes/tags/prioridad; desempate por persistentModelID estable),
así todos los dispositivos de la cuenta borran los mismos perdedores y
el grafo converge a una copia, nunca a cero.
- CloudKit private DB por Apple ID (sin CKShare) → jamás cruza cuentas de
Family Sharing.
Junto con el uniquingKeysWith previo, la app deja de crashear y limpia los
platos duplicados en cada arranque, sin borrar la BD.

Foundation for 2.1 family sharing (CKShare needs these models + container).
SwiftData cannot share across Apple IDs today, so 2.0 ships true multi-device
sync for the same account instead:
- Models made CloudKit-compatible: dropped @Attribute(.unique) on all 5,
inline defaults on every attribute, WeekPlan.slots stored as optional
relationship (name preserved → lightweight migration) with non-optional
slotList facade; ~73 call sites renamed.
- Container: cloudKitDatabase .automatic, falling back to the local-only
store when CloudKit is unavailable; failures recorded to Crashlytics.
- Entitlements: iCloud CloudKit service (container already existed);
remote-notification background mode for push-driven sync.
- Legacy KV snapshot sync (ICloudSyncService) stays inert when CloudKit is
active — kept only for 1.x devices.
- DeduplicationService collapses cross-device duplicates deterministically on
launch (settings singleton, default tags with tagId remapping, same-week
plans).
- Note: AppSettings.isPremium now syncs across same-Apple-ID devices; StoreKit
(PremiumSyncService + Transaction.updates) remains the source of truth and
reconciles on every launch/foreground.
All 21 unit tests pass, including ICloudSyncPremiumIsolationTests.
