🎯 Fundamental Fix for Ball Escape Issues

We have implemented a fundamental solution to the issue where balls would escape outside the stage boundaries. We have focused particularly on areas where stage boundaries meet, where this problem occurred most frequently, and significantly improved the system to prevent balls from escaping outside the stage.

These improvements provide a more stable and comfortable gameplay experience.
