Four real run cycles, rolled one-call-one-row through a new _runroll.py

The old run frames were generated one at a time and it showed: 91/110/92/98 px
of body-width drift, duplicated poses drawn differently, no racket. Each
character (player m/f 6 frames, opponent m/f 8) now comes from ONE 4K call
anchored on a composed identity reference of its settled frames — the broken
run art stayed out of the reference on purpose. Stride-gated, cut with _fine,
judged by eye per roll. drawChar probes run8/run6/run4/run2.

Side effect: the male opponent's old run art faced LEFT against the
art-faces-RIGHT convention — he had been moonwalking right since install.
Fixed by drawing the new rows to the convention.

Pipeline lessons recorded in PROJECT.md (the model negotiates the count; a
back view has no direction; the racket clause goes early and loud).
