Subject: [PATCH] fix: add slug auto-generation fallback for articles without
 slugs

- Add generateSlug() helper to create URL-friendly slugs from titles
- Apply slug fallback in syncArticles() and syncSingleArticle()
- Handles articles created before slug field was added to schema
- Prevents 'slug cannot be null' database constraint errors
