CompositorHintResolver class

Target position from the compositor — the engine's main resolver.

Mechanics (verified against Flutter 3.47):

• FollowerLayer.getLastTransform() (layer.dart:2707) stores the leader transform, recomputed every frame by the compositor at addToScene — scroll/re-layout/animations update the position with zero manual measuring from Dart;
• LayerLink.leaderSize (proxy_box.dart:4510) is written by the leader on every layout of the target.

The object captures a RenderFollowerLayer (the render object of CompositedTransformFollower) once at construction and reads the layer on each resolve(). The source is the follower itself, not link.leader: LeaderLayer has no getLastTransform method.
