Francis Chalissery be33f80bc6 [codex] Read buffering metadata from response events (#31064) ...

## Summary

- read optional faster-model metadata from streamed buffering payloads
- use the buffering payload itself to determine whether buffering UI
should be shown
- retain the existing header value as a compatibility fallback when the
payload omits the field

## Behavior

An object-valued buffering signal now enables the buffering UI. The
response event's faster-model field takes precedence when present, while
omitted fields fall back to existing response metadata. An explicit null
leaves the retry target unset.

## Validation

- `just test -p codex-api`
- `just fix -p codex-api`
- `cargo fmt --all -- --check`
- `git diff --check`
