集成新的Beaver后端服务到应用实例中，替换原有的nanobot实现。 主要变更包括： - 在Dockerfile和环境配置中添加Beaver相关路径和配置变量 - 更新工作目录结构从.nanobot到.beaver - 实现Beaver引擎加载器，支持配置文件加载和工具组装 - 添加内置工具如ListDirectoryTool、ReadFileTool、SearchFilesTool - 更新消息处理流程，支持通道适配器和网关模式 - 重构技能系统，支持显式工具提示和嵌入式检索 - 改进错误处理和生命周期管理 此变更使应用实例能够使用统一的Beaver后端进行AI代理运行时管理。

"""Beaver 内置 skill_view tool。
|
||
|
||
这个工具对应 Hermes 风格的显式 skill loading path：
|
||
1. skill 正文默认不会长期塞进 system prompt
|
||
2. 模型若想查看某个 skill 的完整正文或支持文件，必须显式调用 `skill_view`
|
||
|
||
这样 skill 的按需展开路径会保持显式，而不是依赖 prompt 里长期堆目录信息。
