Core Release v1.5.21

• fix: preserve extra_content on ChatAssistantMessageToolCall so provider-specific tool-call metadata (e.g. Gemini thought_signature) round-trips losslessly through the gateway (thanks @nghodkicisco!)
• fix: surface Anthropic prompt-cache diagnostics (cache-diagnosis-2026-04-07 beta) via new CacheDiagnostics/CacheMissReason schema, reporting the first cache-prefix divergence point on chat and responses APIs
