feat: 重构为 Monorepo 架构并实现 HTTP Server

架构变更: - 采用 pnpm workspaces 实现 Monorepo 结构 - 将现有代码迁移到 packages/core - 新增 packages/server HTTP 服务层 Server 功能: - REST API: 会话管理、工具管理、配置管理 - WebSocket: 实时双向通信支持 - SSE: 服务端事件推送 - Hono + Bun 作为运行时 API 端点: - GET/POST /api/sessions - 会话 CRUD - GET/POST /api/sessions/:id/messages - 消息管理 - GET /api/sessions/:id/events - SSE 事件流 - WS /api/ws/:sessionId - WebSocket 连接 - GET/POST /api/tools - 工具管理 - GET/PUT /api/config - 配置管理
