    Interface McpUiToolResultNotification

    Notification containing tool execution result (Host → Guest UI).

    The host MUST send this notification when tool execution completes successfully, provided the UI is still displayed. If the UI was closed before execution completes, the host MAY skip this notification. This notification is sent after McpUiToolInputNotification.

    The result follows the standard MCP CallToolResult format, containing content for the model and optionally structuredContent optimized for UI rendering.

            _meta?: { [key: string]: unknown };
