• arrow) and MeshProfilePlotDialog (which wires this tool's markerChainageChanged to the profile chart's cursor, and the chart's cursorChainageChanged back to the overlay).

Behaviour:

• Left-press within a few pixels of the profile line begins a drag and snaps the marker to the nearest point on the line.
• Mouse-move projects the cursor onto the line → chainage, moves the marker, and emits markerChainageChanged so the chart cursor follows.
• While dragging the arrow is painted live in the tool overlay (immediate) and the scene-overlay arrow is hidden; on release the scene arrow is restored at the final position.
