/*
 Validates (and can fix) the language bar on wiki pages.
 Checks that the first line starts with the globe bar and that links are absolute
 and point to the expected EN/IT/DE/FR/ES/zh-CN pages for that filename.
 Usage:
   node scripts/validate-wiki-languagebar.js           # report only
   node scripts/validate-wiki-languagebar.js --fix     # update files in-place
