jif 62fb56ee56 Route Guardian inference through dedicated endpoints (#40892)
## What changed

- Add the opt-in `features.guardianv2.free_guardian` setting to route eligible
  Guardian reviews to `/guardian` and asynchronous classifications to
  `/guardian-classifier`.
- Support endpoint selection for both HTTP and WebSocket Responses clients,
  including endpoint-aware connection reuse.
- Keep `/responses` for API-key authentication, custom provider URLs,
  non-Guardian models, and configurations where the option is disabled.
- Omit routing hints and `service_tier` from requests sent to the dedicated
  Guardian endpoints.

## Testing

- Cover route selection across authentication modes, provider URLs, HTTP
  fallback, WebSocket review sessions, and classifier sampling.

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.
