detention-tables: measure STANDING ORDER's Act Two fight, and hold it

A second scenario gets pack-tables' arrangement: four configs (Teague plus
one, three or five wardens) against the declared six and the four-player
cut, 2000 runs at seed 11, cap 400, recorded to detention-baseline.json,
citeable as "detention", and --check added to npm run check.

standingorder joins all-specs' SCENARIOS, and simulate.mjs now reads that
list instead of keeping its own copy, so a new cast is fightable the day it
is registered. The lethality, focus and pack baselines are unchanged.
