+/**
+ * 文件用途：Bash工具实现，提供命令执行、权限管理、输出截断等功能
+ * 作者：TRAE
+ * 创建日期：2026-02-01
+ *
+ * 输入输出签名：
+ * - 输入：command（命令字符串）、timeout（超时毫秒）、workdir（工作目录）、description（命令描述）
+ * - 输出：{ title, metadata: { output, exit, description }, output }
+ *
+ * 依赖列表：
+ * - zod@latest
+ * - web-tree-sitter@latest
+ * - tree-sitter-bash@latest
+ * - bun@latest
+ *
+ * 与其他模块交互方式：
+ * - 调用Instance.directory获取项目根目录
+ * - 调用ctx.ask()请求权限（external_directory、bash）
+ * - 调用ctx.metadata()更新元数据
+ * - 调用ctx.abort监听中止事件
+ * - 调用Shell.killTree()终止进程树
+ *
+ * 其他备注：
+ * - 相关文件：bash.txt（工具描述模板）
+ * - 支持Windows、Linux、macOS多平台

+ * - LPT1-9（并行端口）
