0.34.3 — Motion Polish — Drag Fix

Fixed: Cards could not be dragged between columns after the v0.34.2 motion polish — the motion.div → plain <div> replacement in Card.tsx accidentally dropped the draggable HTML5 attribute and the {...dragHandlers} spread that wire onDragStart / onDragEnd on each card. Without draggable the native HTML5 drag event never fired, so the board could not move tasks between columns even though the click-to-open drawer still worked. Restores draggable and dragHandlers on the card container; no other behavior changes.
