Interface QueryDimensionInfo

Per-dimension metadata the inverse-query needs: the name to look the transform entry up by, plus enough to know where a DISCRETE dimension's values may sit (see the no-preimage rule in invertNdTransformForQuery).

Structurally a subset of DimensionMetadata, so callers pass viewState.dimensions straight through.

interface QueryDimensionInfo {
    name?: string;
    discrete?: boolean;
    step?: number;
    range?: readonly [number, number];
}
