Added a test macOS build

I uploaded a test build for macOS. When I double-click on "Ed," it opens a console window and runs the app, but obviously it's my dev machine.

Give it a try and let me know how it goes. You may or may not need .net 8.0 installed. I built it as a "self-contained" package, but have no idea how well it works, and it seems there aren't many people building macOS apps with .net, so I didn't find much resources on the best practices XD. Hehe.
