Order Repository Pattern

The order repository example models an application persistence boundary that stores orders, queries through a Specification<OrderRecord>, rejects duplicate keys, and can be imported through IServiceCollection.

var services = new ServiceCollection();
services.AddOrderRepositoryDemo();

using var provider = services.BuildServiceProvider();
var workflow = provider.GetRequiredService<OrderRepositoryWorkflow>();
var summary = await workflow.RunAsync();

The example includes fluent and source-generated repository factories plus TinyBDD coverage for add/get/query, duplicate handling, and DI import.
