Enable automatic PR merge and Netlify deployment

Changes:
- Add auto-merge functionality to workflow after successful build
- Add automatic Netlify production deployment step
- Capture PR number from create-pull-request action
- Wait for merge to complete before deploying
- Add NETLIFY_AUTH_TOKEN and NETLIFY_SITE_ID secrets

Why:
- Eliminates manual PR review and merge step
- Automatically deploys new articles to production
- Complete end-to-end automation from detection to live site
- No human intervention required for routine article additions

Result:
- Workflow now runs fully automatically every 24 hours
- New articles detected → validated → merged → deployed
- Live site updates without manual intervention
