/**
 * One-shot news poll — for cron users who don't run the server 24/7.
 * Fetches EDGAR + PR-wire feeds once, runs the pipeline, runs retention,
 * prints stats, exits.
 *
 * Usage:
 *   npm run news:poll
 *
 * Crontab example (every 15 min, market hours, weekdays):
 *   *\/15 9-16 * * 1-5 cd /path/to/market_screener && npm run news:poll
 *
 * If the server runs continuously, its built-in scheduler covers this —
 * set NEWS_POLL=off on the server if you prefer cron-driven polling.
