Version: 0.9.64.dev.260503

后端：
1. 服务级 outbox 基础设施全量落地——新增 service route / service catalog / route registry，重构 outbox engine、repository、event bus 和 model，按 `event_type -> service -> table/topic/group` 统一写入与投递，保留 `agent` 兼容壳但不再依赖共享 outbox
2. Kafka 投递、消费与启动装配同步切换——更新 kafka config、consumer、envelope，接入服务级 topic 与 consumer group，并同步调整 mysql 初始化、start/main/router 装配，保证各服务 relay / consumer 独立装配
3. 业务事件处理器按服务归属重接新 bus——`active-scheduler` 触发链路，以及 `agent` / `memory` / `notification` / `task` 相关 outbox handler 统一切到新路由注册与服务目录，避免新流量回流共享表
4. 同步更新《微服务四步迁移与第二阶段并行开发计划》，把阶段 1 改成当前基线并补齐结构图、阶段快照、风险回退和多代理执行口径
