C14: the generated Go and TypeScript of every seat follow the definitions

Written by seatgen at c62650e4 (GEN3) with mesh-sdk b19fc7fa (reader release): the seat mesh-grants new,
every TypeScript contract as index.js with index.d.ts, events with subject and stream. mesh-watchdogs gains
its family, which a definition with events needs. Written with the reader as it is: the field needs-approval
(node-login-shell) and the section bodies (mesh-conditions) are unknown to it, so they were laid aside for
the run; nothing generated carries either.

Builds: design 47 G §339, §341, §261, §389
