feedback1 gaps: bots skip strategies built around a bond the mode switches off

GameData.bandBondIds reads a band's tie from its own data: the bond names
in <...> of its text (the official note naming the bond among them) and
the bond ids / bond pools of its blackboards (choices.json pools[pool].bond
for pool_char_later). botPickBand weighs a band tied to a bond in
modeInactiveBonds 0, keeps one rng draw per pick and falls back to the
default band when every offered band is excluded. In 标准 潘格尼尼,
克莱门莎 and 玛恩纳 are no longer picked (seeds 1-200: 5/200 solo and
23/800 co-op before, 0 after); the other modes keep the same picks.
