Yunxiao Api Client Abstraction With Authentication

** - Yunxiao MCP Server provides AI assistants with the ability to interact with the [Yunxiao platform](https://devops.aliyun.com).

Unique: Centralizes Yunxiao API client logic in a single YunxiaoClient component, providing consistent authentication, error handling, and request formatting across all tool implementations rather than duplicating HTTP logic in each tool

vs others: Reduces code duplication and improves maintainability compared to tools making direct HTTP calls, with centralized authentication and error handling that scales as new tools are added
