+     *
+     * Unlike sendMessage which triggers follow-up actions, context updates
+     * inform the model about app state without triggering responses.
+     *
+     * **Context Persistence:**

+     * - Only the most recent update is sent to the model

+     *
+     * - **MCP Apps:** Uses native protocol feature for pure context updates
+     * - **ChatGPT:** Uses setState/setWidgetState internally
+     *   - Context persists for the widget's session lifetime
+     *   - Both setState() and updateModelContext() expose data to the AI model
+     *   - Use setState() for persistence-focused use cases

+     *   - **Important:** Be mindful of data size when sending large structured content,
