Collapsed controls now reflect active state\n Value prop: A closed panel can still report what it is doing.\n - Show a compact active count when the control surface is collapsed.\n - Surface a short summary of active search/filter state in the collapsed bar.\n - Keep the `Clear` action and full active-filter line inside the open panel.\n\n3.
