Finish the roster: brute wounds, the chair spectator, the last boy frames

The two that kept failing land as two-figure sheets — a dragged pole or a
held-up chair is wide enough that four to a sheet either merge into one frame or
run off the canvas whatever margin the prompt asks for. The chair spectator came
out the best of the lot (0.15-0.24 to 0.42-0.52).

Also caught x_boyrun3 and x_boyrun4 sitting at the old fidelity next to the two
frames of the same run I had already redrawn — my batch list only covered half
the cycle.

The roster now averages 0.341 inner-edge density across 111 character sprites,
against 0.237 for z_mach2. What is deliberately left alone: the chapter bosses,
the judge, the ball machine and the weapon icons — Oliver named those as the ones
that were already right.
