DigiaOverlayController class

Internal controller that coordinates between DigiaInstance (imperative) and DigiaHost (declarative widget tree).

Mirrors Flutter's own controller pattern (ScrollController, AnimationController, TextEditingController) — a plain Dart object that bridges the SDK world and the widget tree.

Never exposed to app developers.
