WPF UI Files

Next release of WPF UI mainly consist of fixes provided by our wonderful community. Many people have put their hearts into working on the library.

The new version is now available on NuGet:
https://www.nuget.org/packages/WPF-UI/4.1.0

We have also added support for .NET 10 and several experimental tests with the amazing FlaUI library.

Instructions for GitHub Copilot and other agents working with MCP have also been added. I hope this will help with documentation in future releases.

Special thanks go to @Nuklon for numerous quality of life improvements, Win32 refactoring, and a number of general library performance enhancements. @chucker also added corrections and kept track of many of the changes that were made. @apachezy and @jbryknar added valuable improvements.
I would like to thank everyone else who contributed their time and enthusiasm.
