public final class UseCaseKey<I,O> extends Object
Type-safe key for use case registration and invocation. Provides compile-time type checking instead of string-based dispatch.

Usage: 


 // Define keys as constants
 public interface MyUseCases {
     UseCaseKey<CreateInput, Result<Entity>> CREATE = UseCaseKey.of("create");
     UseCaseKey<String, Result<Entity>> FIND = UseCaseKey.of("find");
 }

 // Use in DSL
 HexaFun.dsl()
     .useCase(MyUseCases.CREATE)
         .validate(...)
         .handle(...)
     .build();

 // Type-safe invocation
 Result<Entity> result = app.invoke(MyUseCases.CREATE, input);
