/**
 * Shared candidate-id resolver used by both `engine.list()` and
 * `engine.aggregate()`. Reads the visibility-index watermark once,
 * fans every supported filter dimension out to its query helper when
 * the watermark is current, and intersects the results with the
 * existing tag/attribute resolution.
 *
 * Returns `null` when no filter narrows the candidate set — the caller
 * falls back to a full `wf:` prefix scan with post-filtering.
