The bench learns to host the living: two player slots for run-cycle tuning

Oliver: "add a normal player male and female to the hidden bench and let it
run there." The fam walk (up/down) now runs two slots past ZFAMS — PLAYER
MALE and PLAYER FEMALE. In a living slot the racket zombie steps outside the
frame, G.hideO lifts (splatter set it when the match turned), and the real O
runs the walk stop's own back-and-forth at the classic CPU's speed class, so
the cadence on the bench is the cadence the game plays. SK() reads the slot
for the _f suffix, so both tours review without touching the picked tour.
The HUD swaps the wound readout for the tuning one: runHz and aiSpeed, the
dials a live session turns through T.TUNE. T also gains a keyPressed alias.
