Cut v1.35.0 release

[neoaggelos]

Scheduled to happen: Wednesday, 17 Dec 2025

Note for v1.x.0 releases: Having this issue in open state will stop the
periodic run of krel fast-forward
to avoid conflicts with releases running in parallel. The fast-forward will
automatically stop once the v1.x.0 tag is available.
