后端：
1.收口阶段 6 agent 结构迁移，将 newAgent 内核与 agentsvc 编排层迁入 services/agent
- 切换 Agent 启动装配与 HTTP handler 直连 agent sv，移除旧 service agent bridge
- 补齐 Agent 对 memory、task、task-class、schedule 的 RPC 适配与契约字段
- 扩展 schedule、task、task-class RPC/contract 支撑 Agent 查询、写入与 provider 切流
- 更新迁移文档、README 与相关注释，明确 agent 当前切流点和剩余 memory 迁移面
