Haddock dead-link CI failures on master

Tracking issue for post-merge `Update github pages` workflow failures on the haddock-links check. The Deploy step skips on failure, so the published docs site stays at its last good revision until this issue is resolved.

## How to fix

For each package listed under `=== Actionable — fix these ===` in the failing run:

1. Check the package's source repo for a published Haddocks site (gh-pages, CloudFront, etc.).
2. If found: append the base URL to `IOG_DOC_BASES` in `scripts/fix-haddock-links.sh`.
3. If genuinely unpublished: add the package name to `KNOWN_UNDOCUMENTED`.

Then re-run the workflow from the Actions tab. Close this issue once the workflow goes green again.
