textlint の --cache オプションが活きるのは、検査対象のファイルのタイムスタンプを維持できる環境だけということかな。

this.fileCache = fileEntryCache.create(config.cacheLocation);

usecheckSum: Whether to use md5 checksum to verify if file changed. If false the default will be to use the mtime and size of the file. https://github.com/jaredwray/file-entry-cache?tab=readme-ov-file#createcachename-directory-usechecksum
