docs(M03): accept M2 mesh load pipeline state

Work-Package: M03-RND-M2-MESH-LOAD-PIPELINE-001
Agent: sindo-main-codex
Tests: post-merge pipeline, classifier, materials, shutdown, facade, internal-access, manifest, documentation and coordination gates pass
Fidelity: preserves request polling/completion order, statuses, metrics and shutdown drain; asset-backed visual parity remains unclaimed
