ludic deps: the reach bitsets hold 30 states to a word, not 60 - an int is 32 bits, so states 32 apart shared a bit and a function could reach fewer states than it takes; examples/state/reach_wide.ludic and a deps case hold it; reseeded (bootstrap-cfree fixpoint)

# ludic deps: states numbered past a word's 32 bits are still counted apart. S00 and S32 once shared
# a bit (an int is 32 bits and `1 << 32` wrapped), so `pair` reached 1 and `all4` reached 2
