- response.go: errorx.As/val.Code() 换成 errors.As(errorx.ErrorInterface) 取 GetCode()，文案改用 Msg(ctx) 按请求语言渲染（errorx v1.2 起错误值只保存语言， 渲染时再传 ctx）。 - FormatMessage: langx v0.1 起未知 key 的默认码从 200 变成 -1，命中默认码时 回落到 SetDefaultSuccessCode，保持升级前 code:200 的行为。 - go.mod: github.com/yuninks/errorx v1.2.0 / github.com/yuninks/langx v0.1.0。
