Join 11: the merged heads compile where no area's fix is owed

The join's importers name the delivery repository's moved contracts and sdk
(MV1), node-tools' tests use mesh-sdk's gate, the duplicate node-engine claim
rule of the reader release gives way to G's, and the assigner names its first
watched branch, never a constant. The seat holders' AnswerSeat callers are
area 6's.

Builds: design 47 G join 11 (merge of fix round 11)
