## Why
Responses websocket connections use `tokio-tungstenite`. When DNS
returns an unusable native IPv6 address before a working IPv4 address,
sequential dialing can consume Codex's outer websocket timeout before
reaching IPv4. The merged fork change adds Happy Eyeballs-style
alternate-family racing so websocket dialing matches the recovery
behavior already present in the HTTP path.
## What Changed
Advance the workspace `tokio-tungstenite` patch from `132f5b39` to
merged commit `e5e64b86`, and update the matching lockfile source. The
new revision comes from
[openai-oss-forks/tokio-tungstenite#1](https://github.com/openai-oss-forks/tokio-tungstenite/pull/1).
