Enhance enemy AI and area connectivity

- Introduced area grid management in WolfEngine to track player-connected areas.
- Updated enemy behavior to consider area connectivity when alerting and moving.
- Added debugging logs for enemy states and movements to assist in tracking AI behavior.
- Implemented fallback area generation for levels lacking area data.
- Enhanced patrol behavior for dogs and guards to prevent rapid direction changes after hitting walls.
- Updated tests to validate new area connectivity logic and enemy behavior under various conditions.
