Monkey Patch support + Robust callback tracking
McRogueFace needs to accept callable objects (properties on C++ objects) and also support subclassing (getattr on user objects). Only direct properties were supported previously, now shadowing a callback by name will allow custom objects to "just work". - Added CallbackCache struct and is_python_subclass flag to UIDrawable.h - Created metaclass for tracking class-level callback changes - Updated all UI type init functions to detect subclasses - Modified PyScene.cpp event dispatch to try subclass methods
