Add the borderless, transparent, topmost, click-through DragGhostWindow that hosts a tilted (~-6deg) translucent snapshot of the dragged row, a TaskDragController that owns its lifecycle (snapshot -> show -> follow -> close), and a pure DPI-aware DragHitTest helper (unit-tested) for the cross-window screen hit test. Adds the TaskRowViewModel.IsDragging flag and the 'grabbed' Border.task-row.dragging style (lift + scale + lower opacity + shadow). Not yet wired into the drag source.
