AppTypeRegistry.read() returns private paths to public types

What you did

I was looking at this code to fix a bug in blenvy and found that AppTypeRegistry.read() returns inaccessible types

What went wrong

What I was expecting: Return types in a public form (eg: avian3d::prelude::ExternalForce)
What I got: Return types in a private form (eg: avian3d::dynamics::rigid_body::forces::ExternalForce)

This is actually by design (mostly). By using the true type path, we're far less likely to run into duplicates paths. And prevents registering a type twice with two different paths.

Of course, this is also a technical limitation. The way TypePath and std::any::type_name work doesn't allow for it to rely on how the type is imported. It's given only given the one path.

The one thing TypePath does allow is setting a custom path for a given type. You could potentially make an issue/PR to Avian to have them manually set these type paths to something like avian3d::prelude::ExternalForce.

So for now I'll close this as won't fix

I believe I found the real source of my problem anyway
