refactor: 重构PromptXToolCommand为ToolCommand并移至标准目录

📁 文件重构
- 移动: src/lib/commands/PromptXToolCommand.js → src/lib/core/pouch/commands/ToolCommand.js
- 重命名: PromptXToolCommand → ToolCommand
- 统一: 与其他Command文件保持相同目录结构

🔧 代码更新
Class:
- class PromptXToolCommand → class ToolCommand
- 更新module.exports导出名称

Imports:
- 修正BasePouchCommand相对路径引用
- 修正getGlobalResourceManager相对路径引用
- 修正ToolExecutor和logger相对路径引用

References:
- src/lib/core/pouch/commands/index.js: 更新import和export
- src/lib/core/pouch/PouchCLI.js: 更新commands.ToolCommand引用

📂 目录结构统一
src/lib/core/pouch/commands/
├── ActionCommand.js
├── InitCommand.js
├── LearnCommand.js
├── RecallCommand.js
├── RememberCommand.js
├── ToolCommand.js          # 新位置
├── WelcomeCommand.js
└── index.js

✅ 验证通过
- @tool://calculator 减法功能正常: 100 - 58 = 42
- 所有引用路径正确
- 命名规范统一
- 目录结构规范

💡 重构收益
- 遵循项目命名约定
- 统一Command文件组织
- 简化类名提升可读性
- 便于维护和扩展
