Ahmed Ibrahim e614fad02e [codex] Add comp_hash to model metadata (#27532 )

## Summary
- add optional `comp_hash` metadata to `ModelInfo`
- update `ModelInfo` fixtures for the shared schema change
- keep older model responses compatible by defaulting the field to
`None`

## Why
The models endpoint needs an opaque identifier for compaction-compatible
model configurations. This PR only exposes that value in model metadata;
it does not add it to turn context or change runtime behavior.

Follow-up #27520 carries the value through turn context and rollouts,
then uses it to trigger compaction.

## Stack
- based directly on `main`
- replaces #27519, which was accidentally merged into the wrong base
branch
- functionality follow-up: #27520

## Testing
- `just test -p codex-protocol
model_info_defaults_availability_nux_to_none_when_omitted`
- `just fix -p codex-core -p codex-protocol -p codex-analytics -p
codex-models-manager`

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.
