/**
|
|
* 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.
