A3g item 2a: a definition with a marked verb is read with gated-ended, approvals and the verb by caller

seatdef.Resolve, which the seat generator and every reader of a definition go
through, makes each marked verb by-caller and adds the event gated-ended
(gated-ended.<caller>.<call>, kept last per subject one day) and the verb
approvals (class read); the seat files stay as written. approvals is the
gate's verb, so CanHold asks no holder to name it.

Builds: design 47 G §677, §697; lead answers A-264, A-265, A-266
