fix: a forwarded open focuses the browser window

Single-instance made link clicks look broken: the tab opened instantly,
but in a window parked wherever the browser last was — off-camera and
unfocused — where a fresh launch used to be focused and panned to by the
compositor. On OpenExternal the app now sends focus-window over the
control socket (focus pans the camera and raises). xdg-activation is not
the route: the compositor deliberately answers it with an attention
notification, not focus.

 The other half of click-to-tab latency is inside WebKit: creating a webview
 and spawning its WebProcess is ~200ms, so the WPE host keeps a hidden **spare
