Customer Profile Lazy Load

The customer profile lazy-load example shows a production-shaped deferred profile lookup. It includes a fluent lazy loader, a source-generated lazy loader factory, and an IServiceCollection extension that registers the loader and application service.

Import it into a host:

services.AddCustomerProfileLazyLoadDemo();

For reusable app-level registration without importing examples:

services.AddPatternKitLazyLoad<CustomerProfile>(
    (provider, ct) =>
    {
        var store = provider.GetRequiredService<ICustomerProfileStore>();
        return store.LoadAsync(customerId, ct);
    },
    "customer-profile",
    builder => builder.WithTimeToLive(TimeSpan.FromMinutes(5)));

The example validates that the expensive load is deferred, cached, refreshable through invalidation, and importable through standard Microsoft dependency injection.
