C3D-0063 · Move the 20 CL points to SS-ROAD-CL [MOVE-CL-PTS] done

Moves CogoPoints with the exact description CL from layer 0 to SS-ROAD-CL, the layer already holding the centerline linework. CL YELLOW LINE SPLITS is striping and is not moved. Idempotent, reads back to verify.

C# payload

// Move the CL points to SS-ROAD-CL.
//
// Target chosen from what the drawing already does (C3D-0061): SS-ROAD-CL holds the 4 centerline
// linework entities; SS-V-ROAD-CNTR is empty. Not guessed between the two.
//
// EXACT description match on "CL" only - 20 points. "CL YELLOW LINE SPLITS" (pt 494) is striping,
// not centerline, and is deliberately NOT moved. Idempotent: a point already on the target is
// skipped. Reads back to verify.
