Version 2.8.5

This PR modifies the transitionDuration(using:) method in FloatingPanelController to return 0.0 instead of calling fatalError when the FloatingPanelController instance is not found. This change is crucial for several reasons:

1. Avoiding Crashes in Production: Using fatalError in production can lead to unexpected crashes, which are detrimental to user experience. It's safer to return a default value like 0.0 and handle the scenario gracefully.

2. Improved Stability: By returning 0.0, the application can continue running, allowing for better stability and user satisfaction. This approach also aligns with the principle of fail-safety, where the system continues operating under error conditions.

3. Real-World Case: In our large-scale project, we encountered a crash at this specific point due to the fatalError. Given the size and complexity of our application, it has been challenging to pinpoint the exact cause. Switching to a return value of 0.0 would significantly help us mitigate the issue and maintain app stability while we investigate further.

4. Maintainability: Returning a default value makes the codebase more maintainable and easier to debug, as it avoids abrupt termination and allows for logging or other error handling mechanisms.
