There were up to four APS copies (tmp/aps, tmp/aps-spec, tmp/aps-fresh, and a
component-local client copy) and the briefing, wrappers, and runners disagreed
on which to use. Add ensure-aps.sh (ensure/update/reclone) as the one canonical
tmp/aps checkout, point the gherkin-parser wrapper, architect startup, and all
three acceptance runners at it, and update the architect cheat-sheet.
By specifier.
