新建 internal/middleware/security/coverage_test.go，覆盖：

headers.go 全部函数（原 0% → 100%）：
- applySecurityHeaders: 安全头部应用
- 应各种安全头部配置

Argon2id 密码哈希测试（原 0% → 100%）：
- authenticateArgon2id: Argon2id 认证
- parseArgon2idHash: 哈希解析（有效/无效格式）
- parseUint32/parseUint8: 参数解析

GeoIPLookup.Close 测试（原 0% → 80%）：
- 关闭已初始化的 GeoIP 查找器
- 重复关闭安全性

注：GeoIP 数据库加载和网络认证等函数需要外部资源，
由 integration 测试覆盖。

+// Package security 提供覆盖率补充测试。
+//
+// 该文件针对覆盖率低于 60% 的函数编写测试，包括：
+//   - headers.go 全部方法（0% 覆盖）
+//   - auth.go 的 authenticateArgon2id、parseArgon2idHash、parseUint32、parseUint8（0% 覆盖）
+//   - geoip.go 的 LookupCountry、Close、GetStats（0% 覆盖）
+//   - access.go 的 Check（47.8% 覆盖）
+//   - auth_request.go 的 Process（63.6% 覆盖）
