/**
 * Discovery Entrypoint: Dutchie Locations (From Cities)
 *
 * Reads from dutchie_discovery_cities (crawl_enabled = true)
 * and discovers store locations for each city.
 *
 * Geo coordinates are captured when available from Dutchie's payloads.
 *
 * Usage:
 *   npm run discovery:dt:locations
 *   npm run discovery:dt:locations -- --limit=10
 *   npm run discovery:dt:locations -- --delay=3000
 *   DATABASE_URL="..." npx tsx src/dutchie-az/discovery/discovery-dt-locations-from-cities.ts
 *
 * Options:
 *   --limit=N    Only process N cities (default: all)
 *   --delay=N    Delay between cities in ms (default: 2000)
