Change

• bulk_destroy deletes each key independently of the others and answers 200 with one object keyed by pk: null for a deleted record, the failure's ApiErrorBody otherwise (fastapi-viewsets.not_found for a missing record). perform_bulk_destroy returns dict[K, ApiErrorBody | None].
• ImplMixin.perform_bulk_destroy has a default over perform_destroy: an HTTPException or RequestValidationError becomes that key's ApiErrorBody, any other exception propagates, a repeated key is deleted once. CollectionViewSet and DjangoORMViewSet use it.
• destroy / perform_destroy return dict[K, None]. DjangoORMViewSet.perform_destroy returned {"id": pk}, which failed response validation (500) for a non-string key and did not encode as the declared result in a celery_viewset worker (500 fastapi-viewsets.action_failed, reason: result).
• ChangeEvents publishes only the deleted pks of a bulk destroy.
• TS: DestroyReturnData<K> = Record<K, null>; bulkDestroy() returns BulkDestroyReturnData<K> = Record<K, ApiErrorBody | null>.

Breaking: 0.15.0 for both packages. The TODO entry on the non-atomic Django bulk destroy is removed.

Tests

• Per-key results with a missing and a repeated key; a non-HTTP exception propagates (CollectionViewSet).
• Django: bulk result with a missing key, the others deleted; both results encode through ActionCodec.
• Events: a bulk destroy with a missing key answers 200 and publishes only the deleted pk.
• TS proxy specs for the new answer shapes.
