feature: Copilot Workspace Demo - Add RedBoxDemo example project

[jimbuck]

Add a new example project that displays a red box on a black background and moves with arrow keys.

• Create Ion.Examples/Ion.Examples.RedBox/Program.cs to set up the project, draw a red box, and implement movement with arrow keys.
• Add Ion.Examples/Ion.Examples.RedBox/appsettings.json to configure the window size and title.
• Add Ion.Examples/Ion.Examples.RedBox/Ion.Examples.RedBox.csproj to create a new project file for the RedBoxDemo.
• Update Ion.sln to include the new project.
