sweep [--boot] [0xADDR=VAL...] runs each scene with and without the seeds from
the same baseline and reports which scenes' dialogue changes. Maps a story flag's
reach across the corpus. Finding: the Lily form-A flag 0xa57=1 changes dialogue
in 34/297 scenes (SC0000 186->229, SC0040 111->156, ...) — a pervasive ADV lever,
validating the state-divergence finding at scale. Engine 18/18.
