auto (default): run strict; if the RESPONSE is empty and no ranker
errored, run once more at the recall floor.
strict: never relax. searchHybridMulti passes this for every phrasing,
because relaxing per phrasing lets a previously-empty phrasing reorder an
already-successful search — the decision belongs after the outer fusion.
relaxed: the second pass itself. Terminal: it never recurses.
