Refactor app launch sequence to optimize initialization and reduce launch screen display time. Implement asynchronous SDK initialization for Facebook and VasKit, enhancing performance. Update LaunchScreenView with improved animations and dynamic background effects for a more engaging user experience. Mark initialization states in CoreDataManager and LanguageManager for better synchronization.
