Resolution Flow

Class resolution (Get<T>)

1. Compute key: ATag or T.ClassName.
2. Check if registered.
3. Push key to detect circular dependencies.
4. If lazy and no instance exists, create/store TServiceData.
5. If needed, auto-resolve Create(...) params via RTTI.
6. Instantiate via TServiceData.GetInstance<T>(...).

Note: Get<T> returns nil when missing (no exception).

Interface resolution (GetInterface<I>)

1. Compute key: interface GUID (or ATag).
2. Check if registered.
3. Push key for circular detection.
4. If no instance exists, create TServiceData for interface.
5. If needed, auto-resolve Create(...) params.
6. Return I or throw EServiceNotFound when missing.
