Summary

• Adds a first-class wp_ai_client_request_timeout setting alongside the existing connect timeout setting.
• Separates defaults to a short connect timeout (15s) and longer request timeout (300s) while preserving the existing Data Machine filters.
• Logs and exposes the resolved AI transport profile, including request/connect timeouts, RequestOptions usage, cURL hook state, job, flow step, provider, model, and mode.

Testing

• php tests/wp-ai-client-request-timeout-smoke.php
• php -l inc/Engine/AI/RequestBuilder.php

• git diff --check
• npm run build
• homeboy test data-machine

Caveats

• homeboy lint data-machine still reports the existing repository-wide admin React lint baseline (867 findings), so it is not a clean gate for this branch.
• Existing saved wp_ai_client_connect_timeout values are preserved; operators can now set request timeout separately.

Fixes #1816
