Issue description

In Redot 26.2, editor needs to be restarted in order to recognise newly created/registered GDExtension class (redot-cpp)

Steps to reproduce

1. Open Redot editor first.
2. Open your IDE of choice and create new GDExtension class that extends any type of Godot class.
3. Do necessary registration so that the class is exposed to the editor.
4. Move to Redot editor and you will see the new class won't be detected unless the editor is restarted.
