Usage:
  python run_scrape.py              # scrape CA (default)
  python run_scrape.py TX 3         # scrape TX, 3 pages
  python run_scrape.py CA 5 proxy   # override mode for this run

Set SCRAPER_MODE in .env to switch modes permanently:
  rebrowser   → free, no proxy, headless (default)
  proxy       → set PROXY_URL in .env
  scraper_api → set SCRAPER_API_KEY in .env (free 1000 req/month)
