This is a convenience method for calling tools that support task execution. The server will return a task reference instead of the immediate result, which can then be polled via `get_task()` and retrieved via `get_task_result()`. Args: name: The tool name arguments: Tool arguments ttl: Task time-to-live in milliseconds (default: 60000 = 1 minute) meta: Optional metadata to include in the request Returns: CreateTaskResult containing the task reference Example: # Create task result = await session.experimental.call_tool_as_task( "long_running_tool", {"input": "data"} ) task_id = result.task.taskId # Poll for completion while True: status = await session.experimental.get_task(task_id) if status.status == "completed": break await asyncio.sleep(0.5) # Get result final = await session.experimental.get_task_result(task_id, CallToolResult) N)r)rrtask_metaparams) types RequestParamsMetar send_request ClientRequestCallToolRequestCallToolRequestParams TaskMetadataCreateTaskResult)rrrrrrs rcall_tool_as_taskz,ExperimentalClientFeatures.call_tool_as_task4sP26  '',,4t4E]]//   %% 66!"+"//C8#    " "    sB#B,%B*&B,task_idc K|jjtjtjtj |tj d{S7w)z Get the current status of a task.
