docs(M03): accept M2 runtime mesh finalizer

Work-Package: M03-RND-M2-RUNTIME-MESH-FINALIZER-001
Agent: sindo-main-codex
Tests: post-merge finalizer, classifier, extractor, cache, pipeline, materials, shutdown, facade, internal-access, manifest, documentation and coordination gates pass
Fidelity: preserves refresh version 2 and rebuild/fallback transitions; asset-backed visual parity remains unclaimed
