feat: implement extended scraping with persistent storage and scheduling #2

- Add SQLite database layer for persistent website storage with UUID tracking
- Implement comprehensive analytics tracking (scrape time, URLs found, etc.)
- Add content change detection using MD5 hashing for FAQ, contacts, shipping, terms
- Create scheduled scraping based on sitemap frequency and lastmod
- Add GET /api/shops/:id endpoint for shop details and analytics
- Add GET /api/shops endpoint to list all shops
- Track scrape history with detailed timing and status
- Auto-schedule next scrape after job completion
- Link jobs to shops via UUID for complete tracking
