CODEX SHIPS SAFETY LINK FIX AND MAX REASONING ALIGNMENT

Safety check surfaces in Codex were routing users to stale documentation, and the reasoning picker was mishandling the max effort level—both are now fixed.

The most critical ship is the safety check link update [1], which patches broken Trusted Access URLs and ensures the Help Center surfaces consistently across Bio and Cyber safety surfaces in the TUI. This closes a gap in the previous #30317 work where retry and wait behavior are preserved. In parallel, Codex now treats max as a first-class reasoning effort [2], fixing a catalog alignment problem where Bedrock GPT-5.6 advertises max but Codex was rendering it as lowercase while treating it as an opaque custom value. The fix adds typed ReasoningEffort::Max parsing and serialization without changing the wire protocol or persisted representation. On the infrastructure side, Nagle has been disabled unconditionally on Rendezvous WebSockets [3] to improve latency on exec-server connections, with TCP_NODELAY enabled at both connection endpoints and no feature flags or telemetry overhead added.
