Opening a drawing that xrefs several 3D-heavy DWGs (e.g. Clinic.dwg with 5 discipline files) took ~137s, effectively all of it inside the DWG parser's AcDs SAB blob extraction. Bump the acadrust pin to ceef045, which bounds the AcDs end-marker search so a missing marker family no longer scans the whole buffer per record. Total xref resolve for Clinic.dwg drops from ~97s to ~4s. Also make the post-xref mesh pass incremental: the host solids were already tessellated by the background loader and the merge assigns fresh handles to every imported entity, so `populate_missing_meshes_from_document` keeps the cached host meshes and tessellates only the merged xref solids instead of clearing and rebuilding the whole document.
