👑[Enhancement] 请求添加build指南

### 🥰 需求描述(Description)
请求添加build指南，方便有能力的人自行编译

### 🧐 解决方案(Solution)

github的readme.md更新说明即可。感谢！

### 🚑 其他信息(Other Information)

Start with README.md and inspect the repository's existing build-related information. Add a clear guide for contributors who want to compile SteamTools themselves, using only the project's documented build process. Done means the README explains how to build the project without requiring maintainers to clarify the basic steps.
