/**
 * `wp tmdo cleanup-hp-transients --options` (2.2 PR-080): the HivePress AddOn
 * moved HivePress's per-post transients out of wp_postmeta into wp_options
 * (`_transient_wpdo_hp_pm_*`), where they piled up — 1.15 M rows on dev36. Since
 * PR-081 they live in the object cache when there is one; this removes the
 * rows left behind. Works without the AddOn loaded (as in core CI).
