zeromind.setMetadata

Edit a published world's metadata on ZeroMind — title, description, long body, tags, topics, category, visibility and draft state. draft = false takes a draft world out of draft so players can open it; draft = true with a visibility keeps it a draft meant for that visibility. These are the fields someone browsing the library reads before they ever open the world, which is what makes them different from the world's runtime state (wld.*).

Pass only the fields being changed; the rest are left alone. Refuses a call that changes nothing. Needs Maintainer access to the world, and answers with the updated record.
