Mods that widen field-move rules (use an HM without teaching it, a
rental mon) had to monkey-patch partyKnows, the one function every
field-move path funnels through. Wrap the vanilla check in a hook
instead: next_ is the whole badge-and-knows-move check, so a wrapper
that calls it first keeps vanilla answers winning and only fills the
cases vanilla denies. No hook, no behavior change.
