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.

Per feedback, the model · permission-mode · context line reads better in
the status bar than as a strip above the conversation. Adds a generic,
publisher-agnostic status-bar context slot: a pane publishes a short
string to the `statusbar.context` MessageBus channel and the bar shows
the latest. The active Claude sub-tab publishes (inactive panes stay
quiet, so no race); switching tabs swaps the slot to the focused pane.
Replaces the in-pane ClaudeStatusStrip with a formatStatusLine helper +
PaneContextStatusItem (the status-bar widget) and a StatusItemContribution.
ClaudeSessionHost passes `active` so only the visible sub-tab publishes.
