Captures the brainstormed design to align OtOpcUa with ScadaLink: single role-gated binary, Akka.NET cluster with admin/driver roles, cluster singletons for control plane, per-node actor hierarchy for OPC UA runtime, dual-endpoint warm redundancy preserved with ServiceLevel driven by Akka leader, cookie+JWT auth, Traefik routing, and ScadaLink-style live-edit + deploy model replacing the draft/publish ConfigGeneration lifecycle.
