docs: fix broken links in self-hosting guide

The shared self-hosting snippet renders under every framework section
(built-in-agent, langgraph, ...), and the NavigationLink rewriter makes
absolute links section-relative.

- "Intelligence Platform Works" linked /learn/intelligence-platform,
  which became /<framework>/learn/intelligence-platform (404). The page
  is served at /premium/intelligence-platform in every section.
- The GHCR chart-releases link used the repo-scoped URL for the private
  Intelligence repo (404 for public readers); switched to the public
  org-scoped package URL.
