Flatten the ladder: cap how wide an opponent paints

Oliver: from the Runner on the zombie game is very hard. Measured with
the ring bot: the win rate fell off a cliff wherever an opponent's
width crossed ~3.3 m, the auto-run's reach from the centre (at the
Steward, and again at the Seller), and from there every line could be
painted. Legs and flub decay moved nothing.

Every match opponent's spread is now capped at 3.0 m (matchWideMax),
and the put-away chance runs 0.15 to 0.8 instead of 0.2 to 0.85.
Level 10: the Runner goes from 44% to 68% of points, the Champion from
24% to 33%, with a steady slope between them. New test pins the cap.
v387.
