👑[Enhancement] 让工具箱支持解除b站地区限制

### 🥰 需求描述(Description)

rt，装了工具箱之后感觉再装梯子感觉有点冲突了，不如让工具箱集成解除b站地区限制的功能

### 🧐 解决方案(Solution)
可能可以通过反向代理实现？

The issue proposes integrating Bilibili regional-access functionality into SteamTools, possibly through a reverse proxy, but names no files, entry points, or tests. First clarify the supported platforms, legal and technical scope, and expected behavior; completion criteria and an implementation area would need to be defined before work can start.
