✨ feat(stt-sdk): 新增语音转文字SDK核心包

- 添加workspaces配置支持monorepo包管理
- 创建stt-sdk-core包，包含完整的语音转文字功能
- 实现核心SDK类SttSdk，支持初始化和管理器创建
- 实现事件发射器AGEventEmitter，提供类型安全的事件系统
- 实现错误处理系统SttError，包含错误码和恢复策略
- 实现STT管理器适配器，支持转录开始/停止/查询功能
- 实现RTM管理器适配器，支持频道加入/数据更新/锁管理
- 添加完整的TypeScript类型定义和导出
- 配置ESLint、Prettier、TypeScript等开发工具
- 添加完整的单元测试覆盖核心功能
- 配置Vite构建工具，支持ES模块和CommonJS输出
