Closure in route list

I believe the spark routes command should output closures.

At the moment, the kernel is built in such a way that routes with closures are used for internal needs, so closures are not displayed in the list.

I don't like to use Closure routes, but I agree that `spark routes` should output the routes.

Now we have deleted the internal closure routes, so you can add the functionality easily.
