Purely geometric — it captures a scene polyline and emits it; it never touches a layer. So it is also the capture tool for the terrain-toolbar DEM profile (SWMMVisProjectWindow::activateTerrainProfileTool), which routes the same polyline to RasterProfileSampler instead of MeshProfileSampler.

Behaviour (mirrors MapToolPick2DCells's lasso idiom):

• Left-click adds a polyline vertex.
• Mouse-move shows a live rubber segment from the last vertex to the cursor.
• Double-click or Enter finishes (needs ≥ 2 vertices) and emits profilePathTraced with the vertices in scene coords (sx = mapX, sy = -mapY — the layer convention consumed directly by SWMM2DMeshLayer::sampleZAt / SWMM2DResultsLayer::pickCellAt).
• Right-click undoes the last vertex.
• Escape cancels the in-progress trace.
