The mid-round democratic monster claws when its turn comes

Every creature is born with attackUsed spent — the right way to say
"cannot attack the turn created" for monsters whose flag refreshes
next turn. But the democratic monster's flag budgets its ROUND, so a
mid-round summon arrived pre-spent and bumped harmlessly until the
round rolled over. Creation-turn pacifism now rides justCreated
alone for the monster (checked at the touch), and its round-claw
starts live — folded into rev 18 with the boundary refresh.
