添加三个新测试文件： bytes_test.go - 字节/字符串零拷贝转换测试： - TestB2s: nil 切片、空切片、ASCII、UTF-8、特殊字符 - TestB2s_ZeroAlloc: 验证内存共享（指针比较） - TestS2b: 空字符串返回 nil、正常转换 - TestS2b_ZeroAlloc: 验证内存共享 - TestB2s_S2b_RoundTrip: 往返转换正确性，包括二进制数据 etag_test.go - ETag 生成测试： - TestGenerateETag: 表驱动测试，零时间、大尺寸、负值 - TestGenerateETag_Format: 验证引号包裹的 hex-hex 格式 - TestGenerateETag_Deterministic: 相同输入产生相同输出 - TestGenerateETag_DifferentInputs: 不同输入产生不同输出 ipallowlist_test.go - IP 白名单测试： - TestParseIPAllowList: nil、空、CIDR、单 IP、localhost、无效输入 - TestParseIPAllowList_Localhost: 验证 127.0.0.1/32 + ::1/128 展开 - TestParseIPAllowList_SingleIPv4/IPv6: /32 和 /128 自动转换 - TestParseCIDR/TestParseCIDR_Invalid: 有效/无效 CIDR 和单 IP - TestIPInAllowList: 匹配/不匹配及边界情况 - TestParseIPAllowList_Integration: 端到端解析+检查
