/**
* Integration test to verify that the main TunerStudio Java UI can be loaded.
*
* Note: Due to the complex dependencies and obfuscated nature of the codebase,
* this test focuses on verifying that the TunerStudio class can be loaded
* and basic class reflection works, which serves as a smoke test for the build.
*
* For full UI testing, manual testing or end-to-end tests with a running
* application instance are recommended.
* This test loads the compiled JAR file and verifies:
* - The JAR exists and is valid
* - The TunerStudio class can be loaded from the JAR
* - The main method exists and has correct signature
* - The application can begin initialization
