/**
 * Intent Detection: classify an utterance into an {@link IntentKind} with a
 * confidence, capturing the raw spans (column names, values, directions) it
 * carries. The default detector is lexical: a table of scored patterns, a
 * productionized generalization of the old mock's regex list. It is a pure
 * function of the utterance (the context is available for future
 * schema-aware scoring but the default does not need it), so the highest-scoring
 * matching rule wins and anything unmatched is `unknown`.
 *
 * @see plans/ai-reasoning-layer-spec.md (section 4.4)
