- Add newenglandoil/ package as the primary scraper (replaces fuel_scraper)
- Add cheapestoil/ package as a secondary market price scraper
- Add app.py entry point for direct execution
- Update run.py: new scrape_cheapest(), migrate command, --state filter,
  --refresh-metadata flag for overwriting existing phone/URL data
- Update models.py with latest schema fields
- Update requirements.txt dependencies
- Update Dockerfile and docker-compose.yml for new structure
- Remove deprecated fuel_scraper module, test.py, and log file
