<issue_description>Goal: Include Link response headers for agent discovery (RFC 8288)

Issue: No Link headers found on homepage

Fix: Add Link response headers to your homepage that point agents to useful resources. For example: Link: </.well-known/api-catalog>; rel="api-catalog" to advertise your API catalog, or Link: </docs/api>; rel="service-doc" for API documentation. See RFC 8288 for the Link header format and IANA Link Relations for registered relation types.
