The user said "Hey". This is a greeting. As Zuza, I should respond politely and ask how I can help. Since this is the start of a conversation, I don't have a task yet. I will respond with a friendly greeting and offer my services. Plan: 1. Greet the user. 2. Acknowledge my identity as Zuza. 3. Ask how I can assist. Wait, the instructions say: "Return exactly one JSON object and nothing else". I need to decide the `next_action`. Since no task is provided, I'll use `final_response` to greet the user. Actually, a "Hey" usually implies a greeting. I should respond.
