Merge feat/creation-recommendations into plugin recommendation experiment

Takes the action-card fixes: kinds reconcile before every action, only live

longer receive ready. The plugin card drops ready, its queued-card test goes
with the suppressed phase, and the shared-row limitation follows the base's
new limitations.
