Alexi Christakis 8917244f7d [core] Support interleaved response items (#30876)
## Summary

- preserve reasoning item IDs on summary part and text delta events
- track streamed response items by ID so reasoning summaries can
continue after later items begin
- keep TUI output complete and deduplicated when reasoning and
final-answer events interleave

## Stack

- **1/2: this PR — interleaved item support**
- 2/2: #30752 — wire reasoning summary delivery configuration through
the CLI and app-server

## Validation

- just test -p codex-api preserves_reasoning_summary_item_ids
- just test -p codex-core
interleaved_reasoning_summary_events_keep_reasoning_item_metadata
- just test -p codex-tui
live_reasoning_summary_is_not_rendered_twice_when_item_completes
- just fix -p codex-api -p codex-core -p codex-tui
- just fmt

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 Compact 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).
  • Compaction endpoint

    • Input: CompactionInput<'a> (re-exported as codex_api::CompactionInput):
      • model: &str.
      • input: &[ResponseItem] history to compact.
      • instructions: &str fully-resolved compaction instructions.
    • Output: Vec<ResponseItem>.
    • CompactClient::compact_input(&CompactionInput, extra_headers) wraps the JSON encoding and retry/telemetry wiring.
  • 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 compacted ResponseItem values.
