Update Codex default model to 5.6 Terra or 6.1 Terra #297
Description
What happened?
GPT 5.5 is unavailable on ChatGPT plans, so it should no longer be the default model.
Steps to reproduce
- Delete existing user data
- Setup ChatGPT account inside Diffex
- Warning sign will be shown (GPT 5.5 was removed from plans like 2 weeks ago)
Expected behavior
It selects a supported balanced model, like 5.6 Terra or 6.1 Terra.

I already have a PR ready to update it to 5.6 Terra, but it got auto-closed.
