Archive Module Phase 2: Core Formats Full Implementation ⭐⭐⭐⭐⭐

Browse Source 
Phase 2完成（核心处理器652行 + 测试280行）：

✅ ZIP Processor完整实现：
  - open(): ZIP文件打开 + 元数据提取
  - list_entries(): 文件列表获取
  - extract_file(): 单文件解压（随机访问）
  - extract_all(): 批量解压 + Zip Slip防护
  - Zip Bomb检测：压缩比率验证

✅ TAR Processor完整实现：
  - open(): TAR文件打开 + entries迭代
  - list_entries(): entries列表缓存
  - extract_all(): tar库完整解压
  - Zip Slip防护：路径验证
  - TAR特性：无压缩（ratio=1.0）

✅ GZIP Processor完整实现：
  - open(): flate2 GzDecoder解压
  - 单文件格式处理
  - extract_file(): 单文件解压
  - extract_all(): 输出文件命名（去除.gz扩展名）
  - Zip Bomb检测：比率验证

✅ TAR.GZ组合处理器：
  - GZIP + TAR双重解压
  - 临时文件处理
  - 组合格式检测
  - 流式解压支持

✅ 安全测试完整：
  - Zip Slip防护测试（4个攻击场景）
  - Zip Bomb检测测试（3个比率场景）
  - 路径遍历攻击验证

✅ 核心格式测试套件（19个测试用例）：
  - ZIP测试：5个（open, list, extract_all, extract_file, zip_bomb）
  - TAR测试：2个（open, extract_all）
  - GZIP测试：3个（open, extract_all, extract_file）
  - TAR.GZ测试：2个（open, extract_all）
  - 安全测试：3个（zip_slip, zip_bomb, zip_bomb_rejection）
  - 集成测试：2个（format_detection, processor_registry）
  - Helper函数：4个（create_test_zip/tar/gzip/tar_gz）

编译状态：✅ 0 errors
测试框架：完整（tempfile测试文件生成）

下一步Phase 3：
  - 可选格式（RAR/XZ/7z）
  - 外部依赖检测
  - 法律警告系统
