Channing Conger 21c6d40a44 Add feature for optional request compression (#8767)
Adds a new feature
`enable_request_compression` that will compress using zstd requests to
the codex-backend. Currently only enabled for codex-backend so only enabled for openai providers when using chatgpt::auth even when the feature is enabled

Added a new info log line too for evaluating the compression ratio and
overhead off compressing before requesting. You can enable with
`RUST_LOG=$RUST_LOG,codex_client::transport=info`

```
2026-01-06T00:09:48.272113Z  INFO codex_client::transport: Compressed request body with zstd pre_compression_bytes=28914 post_compression_bytes=11485 compression_duration_ms=0

codex-client

Generic transport layer that wraps HTTP requests, retries, and streaming primitives without any Codex/OpenAI awareness.

  • Defines HttpTransport and a default ReqwestTransport plus thin Request/Response types.
  • Provides retry utilities (RetryPolicy, RetryOn, run_with_retry, backoff) that callers plug into for unary and streaming calls.
  • Supplies the sse_stream helper to turn byte streams into raw SSE data: frames with idle timeouts and surfaced stream errors.
  • Consumed by higher-level crates like codex-api; it stays neutral on endpoints, headers, or API-specific error shapes.
