refactor: restructure game logic and state management into separate modules
- Moved game logic from `game.rs` to `game/mod.rs` and `game/state.rs` for better organization. - Updated `App` to utilize the new `Game` struct and its state management. - Refactored error handling - Removed unused audio subsystem references
