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

// 职责边界：
|
||
// 1. ProcessTriggeredInTx 负责事务内的 trigger -> preview -> notification 编排；
|
||
// 2. MarkTriggerFailedBestEffort 负责事务外的失败回写，避免 outbox retry 前完全没有业务态可查；
|
||
// 3. 接口本身不限定具体实现，便于迁移期由 active_scheduler 模块独立演进。

// RegisterActiveScheduleTriggeredHandler 注册 active_schedule.triggered outbox handler。
|
||
//
|
||
// 步骤化说明：
|
||
// 1. 先做 envelope -> contract DTO 解析与版本校验，明显坏消息直接标记 dead；
|
||
// 2. 再通过 ConsumeAndMarkConsumed 把“业务落库 + consumed 推进”收敛在同一事务里；
|
||
// 3. 若事务返回 error，则 best-effort 回写 trigger failed，并把错误交给 outbox 做 retry；
|
||
// 4. 这里不直接 import active_scheduler 的具体实现，避免 service/events 和业务编排层互相反向耦合。
