Do Not Disturb not working with MacOS 13

[TheSkyentist]

The appearance of the do not disturb icon does work in macOS Ventura 13.5.1.
I believe this is due to the way Focus Modes are accessed in src/misc/dnd.c.
I'm not proficient enough in C or Swift to figure out how to fix this, but I believe the following might be helpful.
The following snippet returns a boolean 0 or 1 depending on whether or not a Focus mode is active: defaults read com.apple.controlcenter "NSStatusItem Visible FocusModes".
Perhaps this can be adapted into dnd.c?

This also appears to be the case in Sonoma (14.x.x).
