Fresh Features & Fixes!

Hey, amazing people! 👋

It’s been a while (yes, keeping tiny humans alive takes a lot of time ⏳), but we’re back with a packed release full of improvements, fixes, and even support for .NET 9! Let’s dive in.

💡 What’s New?
🔹 .NET 9 Support – Staying ahead of the game.
🔹 Package Signing – Our NuGet package is now digitally signed, ensuring package integrity.
🔹 New Abstractions Package – We’ve introduced Wpf.Ui.Abstractions to separate WPF-specific and non-WPF code, making it easier to work across different platforms.
🔹 Updated Fluent System Icons – The latest Fluent System Icons are now included, bringing new symbols and improved visuals.
🔹 Flow Improvements – Moving from main to release instead of development for a smoother workflow.
🔹 Expander Fix – Content height now behaves properly (because we love consistency).
🔹 Performance Boost – Optimized string comparison and excluded unnecessary fields for snappier performance.

…And many more!
