/**
 * Tests for Azure AI Foundry + OCI generic-OpenAI providers with
 * apiFormat=responses routing (PR #2236).
 *
 * Covers:
 *   1. transformRequest strips stream_options when routing to /responses.
 *   2. buildUrl picks the /responses path when
 *      providerSpecificData._omnirouteForceResponsesUpstream === true.
 *   3. The default chat path is preserved for non-responses requests.
