♻️ refactor(tools): 重构工具装饰器系统并优化沙箱与文档注释 (#2147)

* ♻️ refactor(ai): 重构 AI 服务模块并完善文档注释

- 【重构】统一清理并优化所有 AI 服务模块文件的导入语句，将其移至文件顶部
- 【重构】重构 `hooks.py` 中的 `Hooks` 派发逻辑，使用通用管道函数消除重复代码，并引入 `HookPoint` 描述符
- 【重构】重构工具装饰器实现，新增 `toolkit` 类装饰器，优化 `BaseToolkit` 配置合并与前缀处理
- 【功能】Docker 沙箱容器创建时支持自动注入系统代理环境变量并配置 `ExtraHosts`
- 【功能】Jupyter 服务启动前自动清理旧进程并初始化临时目录权限
- 【修复】优化 Pydantic 结构化输出校验失败时的错误信息提取，提供更详细的字段级错误反馈
- 【修复】在 `api.py` 中避免将 `ModelRetry` 和 `ControlFlowExit` 异常错误地包装为 `LLMException`
- 【文档】为 AI 服务、沙箱、工具链、工作流等核心模块补充完整的 Docstring 和类型注释

* 📝 docs(ai): 补全核心模块文档注释并清理冗余代码

- 补全 `run/context`、`run/hooks` 和 `tools/engine/registry` 中类与方法的中文文档注释
- 清理 `tools/providers/builtin/sandbox` 中未使用的 `PythonPluginProtocol` 协议及相关导入
- 规范化部分代码的格式与尾随逗号

* ♻️ refactor!(flow): 重构 Task 为 AgentTask 并优化工作流元数据定义

- 【Breaking Change】将 `Task` 重命名为 `AgentTask` 以避免命名冲突
- 更新 Agent、Team、Workflow 等模块中的类型声明与相关逻辑
- 引入 `AutoNodeMeta` 强类型元数据，替换工作流装饰器中的裸字典定义
- 将 `StepMeta`、`ConditionMeta` 和 `RouterMeta` 统一移动至 `types.py`
- 优化 `RunnableNode` 对上游 `AgentTask` 的处理与拼接逻辑
- 调整团队协作策略中 `FinishAction` 的返回值为完整结果对象

* ♻️ refactor(workflow): 移除人工确认机制并重构错误策略

- 移除工作流节点的人工确认（HITL）与挂起继续机制
- 删除 `auto` 自动化工作流及相关装饰器文件
- 将错误处理策略类从 `types.py` 拆分并移动到新文件 `policies.py`
- 优化节点执行失败时的异常信息格式化输出
- 移除 `WorkflowRunResult` 和 `StepOutput` 中与挂起相关的状态字段

* 🚨 auto fix by pre-commit hooks
