重跑 Dataphin 调度任务实例，支持两种模式：①单实例/批量重跑（operate-instance RERUN）；②重跑下游链路（fix-data，联动重跑根实例及所有下游）。触发场景：周期实例失败需要重跑 / rerun / 重跑实例 / operate-instance / fix-data / 重跑下游 / 修复链路数据 / 实例恢复 / 任务运维。模式①流程：list-projects → list-instances → operate-instance(RERUN) → get-physical-instance-log 验证。模式②流程：list-instances → fix-data(--root-instance-id) → get-physical-instance-log 验证 taskrun。关键点：实例必须属于指定的 project-id；bizdate 默认 T-1；fix-data 的 --root-instance-id 必须传 JSON 对象 {"Id":"t_xxx"}；fix-data 不创建新实例而是创建新 taskrun，验证需查 taskrun 日志。触发词：重跑实例、rerun、任务重跑、operate-instance、fix-data、重跑下游、修复链路数据、实例恢复、补跑实例。
