Refactor and update various components and assets

- Updated WaterBottle scene to change field values and costs, and modified avatar texture and display name.
- Removed unused pencil SVG and its import files.
- Updated Chomp sound effect with a new binary file.
- Modified Diamond bullet behavior to improve tracing logic.
- Increased rotation speed for Laser bullet.
- Adjusted Chick and Hen character attack methods to generate bullets without returning prematurely.
- Updated Rooster character to use PurpleCrystal bullet instead of Pencil.
- Enhanced BulletBase with new properties for energy consumption and animation control.
- Adjusted blend position interpolation in EntityBase for smoother movement.
- Added new Star bullet with its scene and script, including animation setup.
- Updated SVG and import files for new Star bullet graphics.
