interesting tho: is it really a breaking change if those models are not around anymore anyways? using those models would break with v0.8.0 already, right? |

Removes legacy Codex models that are no longer supported by the Codex CLI (rejected with HTTP 400 on ChatGPT accounts) and adds `gpt-5.2` to match the official list at https://developers.openai.com/codex/models. Also updates the examples to use `gpt-5.4` (the recommended default) instead of the removed `gpt-5-codex`.

The Codex
ModelCataloglisted several models that the Codex CLI no longer accepts with a ChatGPT account — calling them returns:This surfaced while trying to run the bundled
examples/codex/*.phpscripts, all four of which hardcodedgpt-5-codexand therefore failed end-to-end.Aligning the catalog with the official list at https://developers.openai.com/codex/models:
gpt-5.4,gpt-5.4-mini,gpt-5.3-codex,gpt-5.3-codex-sparkgpt-5.2gpt-5.2-codex,gpt-5.1-codex,gpt-5-codex,gpt-5-codex-miniAlso:
@see https://developers.openai.com/codex/modelslink to theModelCatalogPHPDoc header so the source of truth is easy to find.gpt-5-codextogpt-5.4(the currently recommended default). All four now run successfully (verified against a local Codex CLI 0.122.0 install).ModelCatalogTestdata provider to match.
