- Add isGoalScored flag to GameState for behavior tree decision-making
- Update SkaterBehavior to skate to center ice (0,0) when goal scored
- Update GoalieBehavior to return to center of goal when goal scored
- Remove update loop freeze from GameScene, now handled by behaviors
- Update CLAUDE.md with comprehensive subsystem documentation
All player logic now contained within the behavior system instead of
GameScene update loop, improving separation of concerns and making
post-goal behavior more realistic (players skate to faceoff positions).
