Retire the legacy NodeInfo, INodeStore, and IContactStore directory model. Route contact projections, protocol observations, persistence, and platform composition through IMeshPeerDirectory across ESP, Linux, and nRF52.
Preserve protocol-specific send/discovery failures through the router and ChatService, restore MeshCore group fallback key handling, classify signed adverts/discovery responses on ESP/nRF52, and enable target logs plus smoke coverage so the next failure has actionable detail.
