pakrym-oai 602d2add6e Persist additional tool definitions in rollout history (#50435)
## Why

`additional_tools` response items were excluded from rollout persistence, dropping their tool definitions from saved history.

## What changed

- Persist `additional_tools` items in both legacy and paginated history modes.
- Expose the variant in generated JSON schemas, TypeScript types, and Python models, with an optional `id`, a `role`, and arbitrary JSON tool definitions.

## Testing

Add a recorder round-trip test that verifies tool definitions survive recording and loading in both history modes without parse errors.

codex-protocol

This crate defines the "types" for the protocol used by Codex CLI, which includes both "internal types" for communication between codex-core and codex-tui, as well as "external types" used with codex app-server.

This crate should have minimal dependencies.

Ideally, we should avoid "material business logic" in this crate, as we can always introduce Ext-style traits to add functionality to types in other crates.
