GameModeManager.cs

Manager component for game modes, handles King of the Hill scoring and a Sudden Death state. It awards periodic points to the player standing in the zone, detects trigger enter/exit to track the zone owner, checks arena shrinker to enable sudden death, and exposes a force multiplier while sudden death is active.
