feat: Complete multi-blog setup with 12 collections and subdomain routing

- Added 12 blog collections: art, bfs, dfs, problems, puzzles, reviews, reflections, vibes, workflows, magic, contests, poetry
- Created content config with glob loaders for all collections
- Added sample posts for each collection
- Fixed TypeScript collection recognition by removing duplicate config
- Made BlogPosts component collection-aware for proper routing
- Created individual post pages ([...slug].astro) for each collection
- Added Netlify subdomain routing configuration
- Updated all references to use neeldhara.blog as main domain
- Fixed navigation links in all-blogs component

Ready for GitHub/Netlify deployment with subdomain support.
