Rewrite TestFakeSourceEmits to synchronize through a channel (it now asserts emission instead of racing on a shared slice and discarding it). Skip the live X11 smoke test under -race: xgbutil's event loop has an internal Quit/Quitting race on shutdown that is never reached in production (Watch runs under a never-cancelled context.Background()).
