Feature Request: Convenient typed API for fetching Godot autoloads

Feature Request: Convenient typed API for fetching Godot autoloads: a task in LegoFlow-SWE (Harbor dataset). Currently, accessing Godot autoload singletons from Rust requires users to manually construct a scene-tree path like /root/MySingleton and call get node as or try get node as . This is…
