新建 internal/variable/builtin_coverage_test.go，覆盖低覆盖率函数： formatRequestTime 测试（原 0%）： - 8 个子测试覆盖零值、毫秒、秒、大值等各种时间格式 SetGlobalVariables 测试（原 0%）： - 正常设置、空配置、覆盖、变量展开 EphemeralGet 测试（原 49.3%）： - 全局变量、回退、server_name、upstream_connect_time - upstream_header_time、body_bytes_sent、request_time - UserValue 响应信息、并发安全 GetSSLClientVerify 测试（原 40%）： - TLS UserValue 设置、对端证书存在、无效类型 init 注册验证测试（原 49.3%）： - 验证 16 个内置变量注册 - 验证 5 个 upstream 变量 - 验证 9 个 SSL 变量 - 验证 host/uri/request_uri/args/method 的 GetterBytes 注册

// - GetSSLClientVerify: TLS 状态分支
