## What changed
- Store a request-logging-disabled `RouteAwareClientPool` in session services and use it for file creation, blob upload, and finalization requests.
- Preserve the existing system-root fallback for transport-default proxy routes, and emit a warning event when that fallback is used.
- Remove the direct `reqwest` dependency from `codex-api` now that uploads use the shared HTTP abstraction.
## Testing
- Add coverage for completing multiple uploads through a shared client pool.

## Why
With system-proxy-aware routing, `RouteAwareClientPool` handles redirects itself so each hop can resolve its own route. That manual path must also respect clients configured not to follow redirects.
## What changed
- Add no-redirect constructors for standard and ChatGPT Cloudflare-cookie route-aware client pools.
- Skip manual redirect handling when the underlying client builder has redirects disabled, returning the redirect response to the caller.
## Testing
- Cover both outbound proxy policies and verify that a no-redirect pool returns the initial `302 Found` response after one request.

## What changed
- Use the configured route-aware HTTP client pool for LM Studio server requests.
- Add connection-timeout support to `HttpClientBuilder` and route-aware pools, and keep LM Studio's five-second limit scoped to connection establishment.
- Verify that LM Studio accepts a response that arrives after the connection timeout has elapsed once the connection is established.

## What changed
- Add `HttpClientBuilder` for configuring default headers, redirects, the
Cloudflare cookie store, and request diagnostics without exposing the
underlying transport.
- Provide factory-backed construction for fixed destinations that respects
outbound proxy policy, alongside explicit direct and legacy
transport-default construction paths.
- Preserve the request-logging setting in `ReqwestTransport`, so disabling
diagnostics also suppresses transport-level URL and request-body traces.
- Add `HEAD`, `DELETE`, and query-parameter helpers to the shared client
wrappers.
## Testing
- Verify builder configuration survives policy-aware construction and custom
CA fallback.
- Verify disabled request logging omits request URLs and bodies from transport
traces.
