Quick CLI tool to test scrapers without the web frontend.

    # Test with a business name (will search Google Maps)
    python tools/test_scraper.py "ClickRent Gran Canaria"

    # Test with max reviews limit
    python tools/test_scraper.py "Starbucks NYC" --max 100

    # Test with full URL
    python tools/test_scraper.py --url "https://www.google.com/maps/place/..."

    # Headless mode (no browser window)
    python tools/test_scraper.py "ClickRent" --headless

    # Verbose logging
