site: repository links use cgit tree URLs; external repo-link audit

- titles.json: map relative doc links to https://git.vgpu.io/open-iov.git/tree/...
  (the host runs cgit; /blob/ URLs do not exist)
- check_site.py: verify every git.vgpu.io URL on every page resolves (HTTP
  status check, cached, with backoff)
- site pages: repository home links point at the .git/ URL
- .publish-manifest.json: revised revision records
