0.17.1 — Column Reorder · Kandown changelog

Fixed: Column reorder drag feedback — dragging a column now shows a clear vertical insertion line between columns, including the final slot after the last column, so the destination is obvious before dropping.
Changed: Column reorder gesture handling — normal columns only start reordering from the gripper handle, preventing card drag and column drag from fighting for the same gesture.
Changed: Column order persistence — reordered columns are saved from the visible board order, so status-derived columns cannot corrupt config indices.
