When ChatView remounted (e.g. tab switch with keyboard still up), the
hook started with keyboardOpen=false and corrected itself only after
the effect ran. That single stale-state render briefly unhid the
executor status bar, which appeared as a blank pane covering half the
input box before the next state update settled it.
useState initializers now call getKeyboardMetrics() lazily on first
render so the very first paint already reflects the live keyboard
state.
