 - Session follow-up 使用 `agentrun send`，由服务端决定内部 steer vs turn。
 - 终态失败重试只使用 `agentrun retry task/<taskId>`：保持同一 task，新增不可变 attempt；先用 `--dry-run` 完成服务端全校验，再以同一幂等键执行真实重试。
 - retry 只接受 Queue 已处于 `failed` 或 `blocked`；`completed`、`cancelled` 和其他状态必须 fail closed。不得复制 task、重置 task、引入本地 scheduler/backoff/judge 或直接创建 runner Job 来模拟重试。
