Description​

System that propagates high score snapshots to MaxScoreObserverComponents.

Each frame, queries all active entities with a MaxScoreObserverComponent and updates them with the current MaxScorePoolSnapshot from the ScorePoolManager. The component's revision-based change detection ensures that downstream consumers (e.g. UI bindings) are only notified when the high score actually changes.
