unparam 死代码清理 12→2（保留 2 处 objectstore 构造函数统一签名）：移除 10 处恒 nil error / 从未使用的结果（getPoWConfigForRoute 的恒 nil *PoWConfig、getSQLiteOverview/getPostgresOverview/getStatus/loadKumaConfig/filterExpectedRoutes 的恒 nil error、rawJSONString/parsePositiveInt 的弃用 bool、buildProxyRoute 的弃用 []ZoneDomain、getLocked 的恒 nil error），同步简化 12+ 处调用方与死错误检查。9 个受影响包测试通过。metric 持平 8（改进在基准之外）。
