Bind immutable configuration as an Instance. Bind an async client, Repository, and service as Lazy Singletons with explicit disposers.

Use getAsync<CatalogService>(). Ark DI initializes the client first, then the Repository and service, while recording the dependency graph.

Create a child and override the Repository with an in-memory implementation. Override its consuming service so the child graph captures the local Repository.

Close the preview Scope, then the application container. Verify that services close before repositories and repositories before clients.
