refactor: Improve Emulator Initialization and Resource Management

Browse Source 
- Refactored SDL initialization process to enhance clarity and error handling, ensuring proper setup of video, audio, and event subsystems.
- Utilized RAII smart pointers for window and renderer management, improving resource cleanup during shutdown.
- Updated audio buffer allocation to use unique_ptr for automatic memory management.
- Enhanced logging for emulator state and initialization, providing better insights during execution.
- Streamlined timing management and frame processing logic for improved performance and maintainability.
