Refactor code for consistency and readability

- Updated import statements to use consistent formatting across files.
- Adjusted method definitions and class constructors for uniform spacing and style.
- Simplified promise handling and error messages in state handlers.
- Enhanced state transition logic in various state handlers.
- Improved quirk animation handling in WaitStateHandler.
- Streamlined animation loading and caching mechanisms in AnimationLoader.
- Updated Vite configuration for aliasing.
