Enhance the feature set of the Flutter Badge Magic Application

The objective of this project is to significantly enhance the reliability, user experience, and maintainability of the Badge Magic application. To achieve this, I will systematically resolve core Bluetooth transfer errors and animation rendering bugs, ensuring stable communication between the app and the LED hardware. Furthermore, I will streamline the user workflow by upgrading the animation preview and introducing intuitive features for managing, loading, and sharing custom designs. Finally, to secure the project's long-term health, I will integrate structured logging and error tracking for rapid debugging, alongside a fully automated CI/CD pipeline to guarantee reliable app store releases.
