0.17.0 — Column Reorder · Kandown changelog

Added: Native HTML5 drag-and-drop column reordering — grip columns by the 6-dot gripper icon (left of column name) and drag to a new position. Columns snap, config updates and persists automatically.
Fixed: Column drag-and-drop handler signature — handleColumnDragOver now works correctly with HTML5 native drag events (removed unnecessary target index param).
