Extract NonRetryableError into its own tanstack-free module and drop the ./api re-export from the Font slice barrel. Importing $entities/Font no longer transitively loads @tanstack/query-core or constructs the QueryClient singleton via the ./api and ./lib (errors) chains — light consumers (domain, types, consts) and unit specs stop paying for TanStack. Note: ./ui still pulls the stores; addressed separately.
