 * Build the Box delta hook.

 * Box keys its tree by folder id and has no recursive listing, so the pull is
 * one `/folders/{id}/items` request per directory. Box does offer an
 * account-wide `/events` feed, which is the cheaper signal and belongs in a
 * push receiver, not here.
 *
 * Fingerprints on `modified_at`, which is what Box stat reports.
