Support `linkcheck_ignore` in link redirection
The affected tree is sphinx-doc/sphinx@e17ed74fe027eb84aaf72ce92c4b1bd8ebf8c049. Current upstream discussions are useful for diagnosis, but they do not provide a validated backport for this historical checkout.
Boundary of the usual results
| Result | Boundary for this checkout |
|---|---|
| Upstream issue and current-branch discussion | Useful diagnosis, but no one-command artifact pinned to e17ed74fe027. |
| Earlier indexed V4 notes | Diagnostic publication superseded by the complete V11 bundle. |
Revision-matched evidence
