Azure OpenAI models report 0 context tokens — supportsUsageInStreaming forcefully disabled
증상
Regression (worked before, now fails)
원인
Agent encountered an unexpected state or unhandled error condition outside the standard error handling path.
해결법
was correct for generic backends but did not account for Azure OpenAI, which fully supports stream_options: { include_usage: true }.
Fix: Add isAzureOpenAIEndpoint() check matching host.endsWith(".openai.azure.com"). For Azure endpoints, only force supportsDeveloperRole: false (Azure rejects developer role) but preserve supportsUsageInStreaming (default true).
Config-only workaround (setting compat.supportsUsageInStreaming: true in models.json) does NOT work because normalizeModelCompat explicitly overrides user-set values for non-native endpoints.
