/**
 * Scheduled Drift-Check Entrypoint
 *
 * Thin, standalone entrypoint for a scheduled (cron) GitHub Actions workflow.
 * It reuses the same logic as the `certification_check_drift` MCP tool but
 * without an MCP round-trip, so a `on: schedule:` job can run it directly with
 * node and fail/annotate the run when a re-certification is recommended.
 *
 * Exit codes:
 *   0 — checked, no re-certification needed (fresh cert, no new advisories).
 *   1 — re-certification recommended (expired / code changed / new advisories /
 *       no completed certification) OR an unexpected error.
 *
 * Env / args:
 *   PROJECT_PATH (or argv[2]) — absolute path to the project. Defaults to
 *   GITHUB_WORKSPACE, else process.cwd().
 *   AGE_WARNING_DAYS — early-warning window in days (default 7).
 *
 * @module action/drift-mode
