MethodBind

Resolves and caches engine MethodBind pointers.

classdb_get_method_bind(class, method, hash) is a dictionary lookup; the returned bind is stable for the process. get is the cold path: generated engine-class wrappers keep one null-checked bind field per method in their companion and call it once, and hand-written callers hold a CachedBind. The (class, method, hash) hash uniquely identifies an ABI-compatible method version, which is how Godot keeps GDExtensions working across point releases.
