Rev 22: the self-stack resolves — one wizard cannot bounce to himself

A democratic monster touching its own creator opens a stack where one
player wears both hats, and doPass matched the attacker first: every
pass "bounced the exchange to the defender" — the same wizard —
forever. Room 928D livelocked there at seq 83; once the boot kick
revived its pump, the automaton politely passed 389 times. At rev 22
a self-stack pass RESOLVES (the claw lands, the game moves on);
older ledgers hold their recorded bounces and replay so. 928D itself
was repaired by truncating the no-op run and lifting it to rev 22,
verified clean and unstuck on a copy before installation.
