Prepare Python SDK 0.144.4 stable release (#33213)

## What changed

- Mark `openai-codex` as stable and align its versioned runtime dependency with Codex CLI `0.144.4`.
- Regenerate the Python protocol models and notification registry from that runtime, exposing the latest requests, responses, notifications, and schema fields.
- Keep `ReasoningEffort` and `ThreadSource` as enum-style APIs while accepting unknown future wire values, and omit `last_turn_id` from the flat `thread_fork` helper.

## Testing

- Cover stable SDK/runtime version matching, forward-compatible enum parsing, and generated client method signatures.
