Sends a visitor message to a session and streams the assistant response back as Server-Sent Events. Public endpoint; no authentication required. The response is a text/event-stream of JSON events (content deltas, rich_content, error, done). When the session is handled by a human operator, the message is stored and acknowledged without an AI response.
