main 仍超过 S3776 认知复杂度上限 15，需要继续拆分。

在复审提交 8f0cdfb 中，main 的按校准规则计算值为 18，超过 issue #911 要求的上限 15。因此，#911 中对应的 S3776 问题仍未解决。该计算方法在基线提交上复现了 issue 报告的五个值（25、42、21、45、29），可作为可靠依据。该值来自规则模型，尚未经 Sonar 分析器确认。

建议将 main 中的结果处理循环及其条件分支提取为辅助函数。提取后，main 应降到 15 以下。提取时应保留现有的退出码、错误输出和结果收集顺序。

将 main 中处理各语言检查结果的循环及条件分支提取到辅助函数，以降低其认知复杂度至 15 以下；保持现有退出码、错误输出以及结果收集顺序不变。
