Fix pnpm

- bump astro 5→6, @astrojs/mdx 4→6, astro-seo 0.8→1.1, sharp 0.33→0.35, plus minor updates
- move local images from public/ to src/assets/
- replace <img> with <Image> from astro:assets (inferSize for remote URLs)
- content schema uses image() helper for local covers
- eager-load above-the-fold images (article covers, hero avatars)
