// bestRecall is the read side of the long-term memory store: the top hit when
// it clears the confidence gate. The index holds BOTH notes and facts, and
// either can win — the caller looks at the returned hit's meta["type"] to see
// which. Facts aren't in the notes table, so this is the only path that can
// answer "when did I last …?" from a captured fact.
//
// The whole hit is returned, not just its text, because "which memory answered"
// decides how the answer is said: a note gets phrased in Maven's voice, a fact
// is read back as stored.
//
// ok=false when the hit fails the confidence gate (see memory.Confident: an
// absolute floor plus a margin over the runner-up) or carries no text.
