Fix Hyprland window ID detection

[postsolar]

PID reporting is not accurate, as it returns parent's PID. This would show up when running Foot terminal in server mode, where it would return the same PID (server's) for every client window. Using window address to identify the window fixes this.

@postsolar thanks for the fix. I'm curious, what is the output of hyprctl activewindow?
