- Addition of all documented commands for `INpnsSystem` and `INpnsUser` as `nullptr` stubs. This includes newly added commands and ensures all known commands have a placeholder.
- Introduction of empty class definitions for `INotificationReceiver`, `ICreateTokenAsyncContext`, `ISubscriptionUpdateNotifier`, and `IFuture` interfaces as specified in the documentation.
- Reversion of the previous change that made `nullptr` stubs call an `UnimplementedMethod` that returned success. Stubs are now back to being `nullptr`.
- Update of the copyright year in `npns.cpp`.
