jif b6a5d5bb14 Preserve Guardian parent response IDs across sampling requests (#45441)
## Why

Running code-mode cells can request Guardian review while the next response is in flight. Clearing the response ID before that response emits `response.created` leaves those reviews without a `parent_response_id`.

## What changed

Keep the latest response ID received in the turn until a later `response.created` replaces it, including across sampling retries.

## Testing

Add regression coverage for reviews before and after a response handoff and for a fresh turn that must not inherit the previous turn's ID. Update retry coverage to expect the last known parent when the retry supplies no response ID.

codex-api

Typed clients for Codex/OpenAI APIs built on top of the generic transport in codex-client.

  • Hosts the request/response models and request builders for Responses and related Codex APIs.
  • Owns provider configuration (base URLs, headers, query params), auth header injection, retry tuning, and stream idle settings.
  • Parses SSE streams into ResponseEvent/ResponseStream, including rate-limit snapshots and API-specific error mapping.
  • Serves as the wire-level layer consumed by codex-core; higher layers handle auth refresh and business logic.

Core interface

The public interface of this crate is intentionally small and uniform:

  • Responses endpoint

    • Input:
      • ResponsesApiRequest for the request body (model, instructions, input, tools, parallel_tool_calls, reasoning/text controls).
      • ResponsesOptions for transport/header concerns (conversation_id, session_source, extra_headers, compression, turn_state).
    • Output: a ResponseStream of ResponseEvent (both re-exported from common).
  • Memory summarize endpoint

    • Input: MemorySummarizeInput (re-exported as codex_api::MemorySummarizeInput):
      • model: String.
      • raw_memories: Vec<RawMemory> (serialized as traces for wire compatibility).
        • RawMemory includes id, metadata.source_path, and normalized items.
      • reasoning: Option<Reasoning>.
    • Output: Vec<MemorySummarizeOutput>.
    • MemoriesClient::summarize_input(&MemorySummarizeInput, extra_headers) wraps JSON encoding and retry/telemetry wiring.

All HTTP details (URLs, headers, retry/backoff policies, SSE framing) are encapsulated in codex-api and codex-client. Callers construct prompts/inputs using protocol types and work with typed streams of ResponseEvent or other endpoint-specific response values.
