+feat: add groqSummarize and createGroqSummarize adapters
+
+Groq now exposes tree-shakeable summarize factories that wrap `GroqTextAdapter`
+in `ChatStreamSummarizeAdapter`, matching the pattern used by OpenAI, Anthropic,
+Gemini, Ollama, Grok, and OpenRouter.

 ### Reasoning
 
 Enable reasoning for models that support it (e.g., `openai/gpt-oss-120b`, `qwen/qwen3-32b`). This allows the model to show its reasoning process, which is streamed as `thinking` chunks:

 ## Limitations
 
 - **Text-to-Speech**: Groq does not currently expose a TTS adapter. Use OpenAI, Gemini, ElevenLabs, or fal for speech generation.
