Slice §V.VA — watches the active map canvas's cursor signal and emits the barycentric Z under the cursor for the active 2D mesh layer.

Wiring:

• The probe attaches to one MapCanvas at a time via setCanvas().
• Active mesh is selected via setActiveMesh(); typically driven by the toolbar's active-mesh combo.
• On every MapCanvas::cursorPositionChanged(double mapX, double mapY) the probe samples Z (scene-space Y-flip applied), throttled to a minimum 16 ms interval to avoid GUI-thread thrash.
