C3D-0038 · READ-ONLY: isolate the stranded sewer easement label [SSE-LABEL-FAR] error

Measures every Civil label on the sewer/prop/easement layers against its parent feature and reports only those more than 60 ft away, with parent handle/type, distance, style and dragged state. Isolates the label that points way out from the drawing. No changes.

C# payload

// READ-ONLY. Which sewer-easement label is stranded far from the thing it labels?
//
// The previous dump was too long to read. This one measures each Civil label's distance from its
// PARENT feature and prints ONLY the outliers (> 60 ft), so the one "pointing way out here" is
// isolated. Also reports whether the label carries a dragged-state offset, because a label whose
// anchor is its parent will snap back when you try to drag it. No changes.
