feat: 完善 Server 层并添加 CLI 和 Web 前端

Server 层增强:
- 添加 Agent 适配层，支持动态加载 core 模块
- 实现 Token 认证机制，支持本地/远程模式
- WebSocket 集成 Agent 实时对话

CLI 模块 (packages/cli):
- serve 命令启动 HTTP Server
- attach 命令连接远程 Server
- API Client 封装

Web 前端 (packages/web):
- React 18 + Vite + Tailwind CSS
- 会话管理侧边栏
- WebSocket 实时聊天界面
- 流式消息显示
