后端：
1.阶段 6 CP4/CP5 目录收口与共享边界纯化
- 将 backend 根目录收口为 services、client、gateway、cmd、shared 五个一级目录
- 收拢 bootstrap、inits、infra/kafka、infra/outbox、conv、respond、pkg、middleware，移除根目录旧实现与空目录
- 将 utils 下沉到 services/userauth/internal/auth，将 logic 下沉到 services/schedule/core/planning
- 将迁移期 runtime 桥接实现统一收拢到 services/runtime/{conv,dao,eventsvc,model}，删除 shared/legacy 与未再被 import 的旧 service 实现
- 将 gateway/shared/respond 收口为 HTTP/Gin 错误写回适配，shared/respond 仅保留共享错误语义与状态映射
- 将 HTTP IdempotencyMiddleware 与 RateLimitMiddleware 收口到 gateway/middleware
- 将 GormCachePlugin 下沉到 shared/infra/gormcache，将共享 RateLimiter 下沉到 shared/infra/ratelimit，将 agent token budget 下沉到 services/agent/shared
- 删除 InitEino 兼容壳，收缩 cmd/internal/coreinit 仅保留旧组合壳残留域初始化语义
- 更新微服务迁移计划与桌面 checklist，补齐 CP4/CP5 当前切流点、目录终态与验证结果
- 完成 go test ./...、git diff --check 与最终真实 smoke；health、register/login、task/create+get、schedule/today、task-class/list、memory/items、agent chat/meta/timeline/context-stats 全部 200，SSE 合并结果为 CP5_OK 且 [DONE] 只有 1 个
