1. 动作优化

1. SummarizeCode动作：用于基于代码进行总结，思考bug、逻辑、todo
  2. CodeReview动作优化：目前强制要求回答问题，有更高的成功率了
2. 数据结构
  1. Document的标准化：Env->Repo->Document，其中Document/Asset/Code都只用Document
    1. 原用于检索的Document改为IndexableDocument
  2. Repo结构引入：用于Document装载与元数据装载
  3. RepoParser引入：写了一个简单的AST parser（后续可能要换tree-sitter），给出了整库symbol
3. 配置优化
  1. 默认更换为gpt-4-1106-preview，以获得最好的效果与成本
  2. 提供~/.metagpt作为配置最高优先级目录，从中读取config.yaml
  3. workspace可以灵活指定了，在config中配置
4. metagpt作为默认命令行，而非python startup.py
  1. 使用新的METAGPT_ROOT生成方式，而非寻找git，以便cli安装
  2. 命令行由fire换为了typer，它会带来相对更好的体验
  3. project_name可以灵活指定了，在metagpt命令行输入中配置
5. 其他
  1. BossRequirement -> UserRequirement
  2. 大量错误文本的修正，增加了可读性
  3. 中量提示词优化，稍微提升了一些准确率
  4. 暂时屏蔽了LongtermMemory相关逻辑，这个逻辑底层调用了langchain的FAISS，会带来~5秒加载耗时
  5. 修复了安装包中的部分描述错误
