Code Review

This pull request introduces several important bug fixes and stability improvements. Key changes include adding try-catch blocks to prevent crashes from unhandled exceptions when launching URLs and creating notifications, and properly closing resources to prevent memory leaks.

I've identified a couple of areas for improvement. In app_detail.dart, the URL launching logic can be simplified to be more robust and avoid redundant calls. More critically, in speech_profile_widget.dart, a resource cleanup call (_speechProvider.close()) was removed from the dispose method, which could lead to resource leaks. I've provided suggestions to address both of these points.

Overall, these are valuable fixes that enhance the app's stability.
