-# 开发者日记@lightjunction
-为了避免和主分支发生大量冲突，新架构设计全部移动至了_internel包
-目前API不稳定，并不希望外部导入这个内部包
-新增astrbot dev子命令用于启动新架构
-概念：
-核心运行时：core runtime 
-核心运行时是主进程
-主要是启动一个后端，这个后端将改为使用fastapi开发
-插件称呼为star
-astrboot，这个名字就和星系相关，插件当然就是一个一个星星了
-Galaxy是星系
-我们的核心运行时需要一个协议和插件对话
-我思考，我们的插件，最好是可以做到和lsp服务器或者mcp服务器那样
-我们需要一套新的协议
-我列举本项目采用的协议如下：
-lsp协议：client
-mcp协议：client + server
-acp协议：client + server 
-abp协议：astrbot protocol client + server (相当于内置插件)
-协议层只管传输
-runtime则负责响应和调度
-异步库使用anyio
-## 覆盖率测试
-需要完善覆盖率测试
-## 类型标注
-需要通过ty类型检查
-避免使用Any cast
-## 代码风格
-需要通过ruff检查
-## 细节
-使用uv run 运行一切，别用python xxxx
