Greptile Summary

This PR fixes a critical state management bug in AlertDialogProvider by replacing useState with useRef for the resolver function, preventing stale closures and ensuring proper promise resolution. Additionally, it adds customizable button styling options (dismissButtonClassName and dismissButtonVariant) and correctly changes from AlertDialogAction to AlertDialogCancel to allow the dialog to close properly.

Key changes:

• Replaced useState with useRef for resolver management to prevent stale closure issues
• Changed from AlertDialogAction to AlertDialogCancel (which properly triggers dialog dismissal)
• Added dismissButtonClassName and dismissButtonVariant props for button customization
• Removed unnecessary setOptions({}) call in handleDismiss
• Added second interactive example to demonstrate new styling features

Confidence Score: 5/5

• This PR is safe to merge and fixes a critical bug
• The changes fix a fundamental state management issue where useState caused stale closures with the resolver function. The switch to useRef is the correct solution. The addition of styling props is straightforward and well-implemented. The change from AlertDialogAction to AlertDialogCancel is semantically correct and necessary for proper dialog dismissal.
• No files require special attention
