docs(M03): accept M2 mesh resource cache state

Work-Package: M03-RND-M2-MESH-RESOURCE-CACHE-001
Agent: sindo-main-codex
Tests: post-merge cache, pipeline, classifier, materials, shutdown, facade, internal-access, manifest, documentation and coordination gates pass
Fidelity: preserves Mesh identity/replacement/final-shutdown lifetime; asset-backed visual parity remains unclaimed
