app.zeens.getEngagement

Like count and the viewer's own like for any record URI, one or a batch. Subject-agnostic: post_engagement is keyed by subject URI and the like hook counts likes on anything, so this serves zeens, events, articles and posts without a branch per lexicon. Pass `uris` to ask about a whole listing in one call -- the profile and studio Zeens tabs list from the author's repo, which carries no engagement, so without a batch each card would need its own round trip.
