Return true when a top-level .md filename looks like a translated
sibling of a canonical editorial artefact (e.g.
executive-brief_ar.md). These files must be excluded from the
top-level fallback scan in extractArtifactHighlight because
their localized H1s evade the English-only generic-heading detector
and would otherwise hijack the English SEO surfaces.
