Build map of base slugs to available languages for cross-language discovery.
O(n) implementation: two-pass approach avoids the previous O(n²) nested iteration that caused timeouts when the news/ directory grew large.
Pass 1 – baseSlug → string[] of languages that have that article. Pass 2 – article.slug → the language list from pass 1.
