Hördle Bot a8867ac42e feat: Add dynamic Open Graph image generation with correct aspect ratio
- Create /api/og-image endpoint that generates SVG with 1.91:1 ratio (1200x630px)
- Prevents logo cropping on Facebook and Twitter
- Uses safe padding (150px) to ensure content is never cut off
- Update default OG image to use dynamic endpoint
- Add SEO testing documentation
