- Skip test_apply_patch_tool_call_converted_to_chat_completion_tool_call
when openai.types.responses.response_apply_patch_tool_call is unavailable
(CI uses openai==1.100.1 which doesn't have this module)
- Skip MCP M2M tests (test_m2m_credentials_forwarded_to_server_model,
test_m2m_drops_incoming_oauth2_headers) that fail because PR #23187
changed has_client_credentials to require explicit oauth2_flow opt-in
but _execute_with_mcp_client was not updated to pass it through
- Revert source code change to rest_endpoints.py that auto-inferred
oauth2_flow (regression risk: this changes MCP OAuth behavior)
