Add sound effects and character scripts

- Imported new sound effects: "Low Boing", "Low Whoosh", and "Pew" with corresponding import files.
- Created a new character script for "Hen" with basic AI and attack functionality.
- Implemented an effect controller script for managing particle effects with one-shot functionality.
