Run the backfill across every news/*.html file under repoRoot.
dryRun: true → don't write any files; still returns a full summary.
check: true → after the dry-run pass, exit-1 if any file still has skipped-no-og-locale (used by CI as a guard).
Exit semantics (when invoked as CLI): 0 — no files needed an update, or all updates succeeded 1 — --check and at least one file is missing the og:locale tag
