C3D-0128 · READ-ONLY: audit the linework just drawn [LW-AUDIT] done

Lists every polyline on the five linework layers with vertex count and length, flags duplicate consecutive vertices, and detects any polyline drawn twice by an accidentally repeated ticket. No changes.

C# payload

// READ-ONLY. Every polyline just drawn, per layer, with vertex count, length and whether it has
// a duplicate consecutive vertex - one run logged "275,275" so at least one exists. Also flags
// exact-duplicate polylines in case a ticket ran twice. Nothing is modified.
