Michael Bolin 9078e32371 Add a route-aware HTTP client pool (#34447 )

## Why

PAC and system-proxy resolution can select a different outbound route for each
request URL. Request creation and route selection must use the same URL while
still allowing transport clients to be reused.

## What changed

- Add `RouteAwareClientPool` and a request builder that resolve the outbound
  proxy route when sending each request.
- Reuse HTTP clients by resolved route, with a bounded cache of 16 routes.
- Preserve request tracing, optional diagnostic logging, custom CA settings,
  Cloudflare cookies, and default transport redirect behavior.
- Export route-aware response and error types, including status, timeout, and
  connection-error helpers.

## Testing

Add tests for exact URL routing, client reuse and eviction, default redirects,
and redaction of URL secrets from debug output.

codex-http-client

Low-level HTTP transport shared by Codex crates.

Defines the request, response, streaming, and transport types used for outbound HTTP calls.
Owns the reqwest implementation, custom CA handling, and ChatGPT Cloudflare cookie policy.
Resolves system, PAC/WPAD, environment, and direct proxy routes for supported clients.

Higher-level retry, SSE, and request telemetry policy remains in codex-client.
