Replace the MessageBus-based pane-context slot with a focus-driven one. Panes keep their status widget locally; the FocusTracker holds the focused pane's widget (activeStatusWidget) and ClidePane conveys it to the shared slot only while its contribution is focused, re-conveying on change and clearing on blur. The status-bar item just renders focus.activeStatusWidget, height-clamped and marquee-scrolled when it overflows. Removes the publish/subscribe race the bus version had. T-150.
