Function notify_refresh 

pub fn notify_refresh() -> usize

Notify every running GUI (if any) that profile state has changed.

Returns the number of listeners that accepted the notification — 0 is the normal case when no GUI is running. Errors are swallowed; this function is safe to call from any CLI exit path.

As a side-effect, sockets that fail to connect with ECONNREFUSED or ENOENT are unlinked: this keeps $XDG_RUNTIME_DIR from accumulating dead socket files when GUIs crash.
