An Avalonia desktop GUI for SabreTools.Serialization that combines the reference behavior of InfoPrint and ExtractionTool.

• Open a file and inspect it through the upstream wrapper factory
• Export the same JSON emitted by IPrintable.ExportJSON()
• Render that JSON as a collapsible tree for easier browsing
• Show the plain-text PrintInformation(...) output from the wrapper
• Pick an output folder and run IExtractable.Extract(...) when supported

The application intentionally keeps its own logic thin. Detection, printing, and extraction all come from the SabreTools.Serialization library so future wrapper improvements should flow into the GUI naturally.

• SabreTools.Serialization.UI.Desktop: primary Avalonia desktop app

env DOTNET_CLI_HOME=/tmp/dotnet-home dotnet restore
env DOTNET_CLI_HOME=/tmp/dotnet-home dotnet run --project SabreTools.Serialization.UI.Desktop

• Printable wrappers populate the JSON tree and printed info tabs
• Non-printable wrappers still show detection details and extract support state
• Extraction uses the wrapper's built-in logic directly, mirroring ExtractionTool
