A keyboard glyph in the bar (WidgetButton, right section by default)
toggles a pause flag at $XDG_RUNTIME_DIR/omarchy-key-visualizer.paused that
the panel and every bar widget instance watch, so a click on any monitor
updates all of them. While paused the panel ignores key state and hides;
the button dims. Also exposes pause/resume/toggle over the key-visualizer IPC
target.
