Create a new release with CVE-2025-64439 mitigation

[alyosha]

Summary

It seems that the changes merged in #531 to bump langgraph and langgraph-checkpoint major versions are slotted to go out in 1.0.0 release.

I'm not sure when 1.0.0 is expected to land, but if not imminent then it might be good to cut a 0.14.0 with the changes from #531 so there is an available version with CVE-2025-64439 mitigation?
