C3D-0069 · READ-ONLY: where are V-NODE-WATR and V-NODE-TEXT used [VNODE-CHECK] done

My filter scan counted only layout block table records, so entities inside block definitions or layers driven by point/label styles were invisible. Checks every block table record for both layers and reports layout vs block-definition usage plus layer state. No changes.

// READ-ONLY. User says V-NODE-WATR and V-NODE-TEXT are used; my scan counted 0 for both.
// My scan only counted entities in LAYOUT block table records (btr.IsLayout). Anything living
// inside a BLOCK DEFINITION, or referenced as a CogoPoint's marker/label layer, was invisible
// to it. Check every one of those places. Nothing is modified.
