feat: windows style window 😜

[Southclaws]

As a daily mac+windows enjoyer, I'd be happy to contribute a Windows option for the window chrome for all my Steve Ballmer fans out there ✊

Looks like https://github.com/charmbracelet/freeze/blob/main/svg/svg.go#L85-L96 is the place to start

Hey @Southclaws, I think this is a great idea. Especially when showing tools work on Windows, etc...

Ideally we would change the --window from a boolean to a string to allow specifying types of window controls. Not sure if that is the best option given it might cause a breaking change unless we can make it so the argument accepts a *string which defaults to macos controls.
