/**
 * One-time maintenance: populate the version-locale availability ledger
 * (`byline_document_version_locales`) for document versions written before
 * the ledger existed. After this runs, `localeFallback: 'strict'` reads can
 * see pre-existing documents; new writes keep the ledger current on their own
 * (createDocumentVersion step 6).
 *
 * Idempotent — safe to re-run. Uses the installation's configured default
 * content locale (resolved from byline/i18n.ts via the server config).
 *
 *   pnpm tsx byline/scripts/backfill-version-locales.ts

 * See docs/08-internationalization/index.md.
