+ * Mutation hook for deleting a shopping list.
+ *
+ * This hook provides automatic cache invalidation. When the mutation succeeds,
+ * it invalidates the shopping-lists query to trigger a refetch of the updated list.
+ *
+ * @returns Mutation object with mutate function and state
+ *
+ * @example
+ * ```tsx
+ * const deleteShoppingList = useDeleteShoppingListMutation();
+ *
+ * const handleDelete = (listId: number) => {
+ *   deleteShoppingList.mutate(
+ *     { listId },
+ *     {
+ *       onSuccess: () => console.log('Deleted!'),
+ *       onError: (error) => console.error(error),
+ *     }
+ *   );
+ * };
