C3D-INSP2403A · Inspect layouts+parcels for hero (read-only) done

List paper tabs (09/10/R4), per-viewport freezes, every parcel area (sf/ac), and hero/boundary/parcel layers. For heroing 1.6 AC on paper 10.

C# payload

// READ-ONLY: inspect the ACTIVE drawing for hero planning.
// - list layouts (paper tabs) + their viewports' frozen-layer isolation hints
// - list every Parcel with area (sf + acres) and its Site
// - list parcel-ish layers and hero layers
