Pull Request Overview
This PR addresses a COM exception (0x8007139F "Expecting object to be local") that occurs when multiple Windows programs utilize WebView2 by isolating the WebView2 user data folder. The solution creates a unique temporary folder for each instance and adds proper cleanup on application exit.
- Create unique user data folder using random filename to prevent conflicts
- Add window closing event handler to ensure proper cleanup
- Implement cleanup logic to remove temporary folder and terminate WebView2 process

WebView2 process is shared per associated user data folder. if there is another program using same user data folder then it's possible that demo throws exception: and fails to run.

If there are unrelated Windows programs that utilize WebView2, starting of demo may result in
System.Runtime.InteropServices.COMException (0x8007139F): Expecting object to be localerror since WebDemo.exe tries to use pre-existing WebView2 process.
