mesh-sdk compiles no seat list and imports no contracts module: catalogue takes its seats from the host, whole seats' names leave it (ADR 0635 §1, §4; issue 1966)

catalogue's working set starts empty and a host gives it the seats it read (UseSeats over SeatsFromDefinitions);
the node-engine's verbs and events take the seat's name from the caller. Tests take their seats from seatlisttest.
