Version: 0.9.60.dev.260430

后端：
1.接入主动调度 worker 与飞书通知链路
- 新增 due job scanner 与 active_schedule.triggered workflow
- 接入 notification.feishu.requested handler、飞书 webhook provider 和用户通知配置接口
- 支持 notification_records 去重、重试、skipped/dead 状态流转
- 完成 api / worker / all 启动模式装配与主动调度验收记录
2.后续要做的就是补全从异常发生到给用户推送消息之间的逻辑缺口
