fix(ai): remove Link header from /raw/* and use window.location.origin for raw URLs

- Remove Link header from global headers scope, apply only to /index.html
- Remove X-Robots-Tag noindex from /raw/* to allow AI crawler indexing
- Use window.location.origin instead of props.url for raw markdown URL construction
- Ensures correct URLs even when props.url points to canonical/deploy preview domains
- Fixes ChatGPT/Perplexity fetch failures on /raw/*.md endpoints
