后端：
1. 阶段 5 schedule 首刀服务化落地，新增 `cmd/schedule`、`services/schedule/{dao,rpc,sv,core}`、`gateway/client/schedule`、`shared/contracts/schedule` 和 schedule port
2. gateway `/api/v1/schedule/*` 切到 schedule zrpc client，HTTP 门面只保留鉴权、参数绑定、超时和轻量转发
3. active-scheduler 的 schedule facts、feedback 和 confirm apply 改为调用 schedule RPC adapter，减少对 `schedule_events`、`schedules`、`task_classes`、`task_items` 的跨域 DB 依赖
4. 单体聊天主动调度 rerun 的 schedule 读写链路切到 schedule RPC，迁移期仅保留 task facts 直读 Gorm
5. 为 schedule zrpc 补充 `Ping` 启动健康检查，并在 gateway client 与 active-scheduler adapter 初始化时校验服务可用
6. `cmd/schedule` 独立初始化 DB / Redis，只 AutoMigrate schedule 自有表，并显式检查迁移期 task / task-class 依赖表
7. 更新 active-scheduler 依赖表检查和 preview confirm apply 抽象，保留旧 Gorm 实现作为迁移期回退路径
8. 补充 `schedule.rpc` 示例配置和 schedule HTTP RPC 超时配置

文档：
1. 更新微服务迁移计划，将阶段 5 schedule 首刀进展、当前切流点、旧实现保留范围和 active-scheduler DB 依赖收缩情况写入基线
