C3D-0377 · Move V-NODE in-block geometry to layer 0 and delete the V-NODE layers [C3D-VNODEKILL] done

Makes every symbol like the control-point example: moves all V-NODE-layer geometry (top-level and inside block definitions) to layer 0 so it inherits each insert's real layer, then deletes the 7 V-NODE layers. Symbols stay whole and connected to their true layers (SEWER_MANHOLE, WATER_VALVE, etc.); the V-NODE layers no longer exist. Verifies none remain.

C# payload

// The HORIZONTAL_AND_VERTICAL_CONTROL_POINT layer is the model: the insert lives on its real
// layer, its guts are NOT parked on V-NODE layers. Make every symbol like that - move all V-NODE
// in-block geometry to "0" (so it inherits the insert's real layer) then delete the V-NODE
// layers entirely. Symbols stay whole and on their true layers.
