Equipment-kind namespaces materialise only their Area/Line/Equipment folder
skeleton on deploy, not the signals under them: EquipmentNodeWalker is fully
built + unit-tested but has no production call site, the composition/artifact
drops EquipmentId-bound tags, and no value source is wired (OpcUaClient driver
factory missing; VirtualTag ITagUpstreamSource unregistered). Documents the
gaps, workstreams, value-path options, and a structure-only-first sequencing.
