## 🎯 核心改进
- **统一沙箱创建**：合并createBasicSandbox()和createSmartSandbox()为单一createSandbox()方法
- **完整process mock**：新增createProcessMock()提供完整的process API支持
- **智能require抽取**：独立createSmartRequire()方法处理依赖解析
- **消除代码重复**：删除~150行重复代码，净减少70行

## ✅ 修复的问题
- ✅ process.cwd()在所有沙箱中可用
- ✅ process.version/platform/arch完整支持
- ✅ 统一的沙箱行为和API
- ✅ 参数化配置，易于维护和测试

## 🔄 API变更
- 新增：createSandbox(options) - 统一沙箱创建入口
- 新增：createProcessMock(sandboxPath) - 完整process对象mock
- 新增：createSmartRequire(sandboxPath) - 智能依赖解析
- 删除：createBasicSandbox() - 已合并到createSandbox
- 删除：createSmartSandbox() - 已合并到createSandbox

## 🧪 测试状态
- ✅ 语法检查通过
- ✅ 基础沙箱功能正常
- ✅ 智能沙箱功能正常
- ✅ process API完整性验证通过

Fixes #107
