feat: enhance SEO and AI indexing with advanced sitemap configuration

Major improvements:
- Enhanced sitemap with priority and changefreq values for all URLs
- Homepage: priority 1.0, weekly updates
- Blog/Services indexes: priority 0.9, weekly/monthly updates
- Individual content pages: priority 0.8, monthly updates
- Portfolio items: priority 0.7, yearly updates

New features:
- Added SEO validation script (validate-seo.js)
- Validates all pages for required SEO elements
- Checks sitemap, robots.txt, and llms.txt configuration
- Can be run before each deployment

Validation results:
- 32 pages validated
- 0 critical issues
- All pages have proper meta tags, structured data, and canonical URLs
- All AI crawlers properly configured (GPTBot, Claude-Web, PerplexityBot, etc.)

Technical details:
- Imported ChangeFreqEnum from @astrojs/sitemap
- Removed deprecated astro-robots-txt package (using manual robots.txt)
- All blog posts, services, and portfolio items properly indexed
