/**
 * R01-N22: deploy-time migration runner.
 *
 * Called by the Docker entrypoint before Apache starts, and by operators
 * directly when applying a new release outside Docker. The web request path
 * (`public/index.php`) only checks `Migrator::pendingFiles()` and refuses
 * to serve when there is anything pending — it does NOT apply SQL itself.
 *
 * Exits 0 on success (including the no-op "already current" case) and 1 on
 * any failure, with a one-line message on stderr. Stdout reports what was
 * applied so the entrypoint log shows it.
