Platform preferences theme detection

[Christopher Schnick]

Lastly I also tried it on macOS. The accent color detection works there, 
but the color scheme detection does not, i.e. it always returns light 
mode. I'm using macOS Sonoma 14.3 with aarch64.

Here are the preferences when dark mode is set in the settings:

So since you are thinking about making this a preview-only feature, I 
don't think there is that much to do to properly handle systems where 
some properties are not supported. Just a few methods to set the default 
value of foreground, background, and accent color would be enough. In 
theory I don't need to know exactly what color observation is supported, 
I only want to have the ability to use my own colors as defaults in that 
case.
