 - 处理：为更新资产解析新增“基于当前可执行文件路径推断 Linux 变体”的后缀选择逻辑；同时调整 Linux 更新脚本，解压后优先搜索与当前运行二进制同名的文件，再回退查找 `GoNavi`。
 - 验证：补充 `internal/app/methods_update_test.go` 回归测试，覆盖 Linux `WebKit41` 资产名选择与更新脚本目标名解析，并执行 `go test ./internal/app -run 'Test(ExpectedAssetNameForExecutableUsesLinuxWebKit41Suffix|BuildLinuxScriptPrefersTargetExecutableBasename|TestFetchLatestUpdateInfo|TestCheckForUpdates|TestBuildWindowsScript)' -count=1`。

+- 根因：ClickHouse 连接协议识别只把 `8123/8443` 视为 HTTP 端口，`8132` 会被误判为 native，导致连接阶段优先走错协议。
+- 处理：将 `8132` 纳入 ClickHouse HTTP 端口识别，并同步更新自动切换日志和错误提示中的端口说明，避免排障信息继续误导。
+- 验证：补充 `internal/db/clickhouse_impl_test.go` 回归测试，覆盖 `8132`、`8123`、`8443` 的 HTTP 判定以及 `9000/9440` 的 native 判定，并执行 `go test -tags gonavi_clickhouse_driver ./internal/db -run 'TestClickHouse(PingValidatesQueryPath|GetDatabasesFallsBackToCurrentDatabase|DetectClickHouseProtocolTreatsHTTPPortsAsHTTP)' -count=1`。

 ### #330
 
 - 根因：查询结果表格已经支持拖拽调整列宽，但 resize handle 没有提供双击自适应逻辑，导致用户只能靠手工拖拽慢慢试宽度。
