OpenCode's @ai-sdk/openai-compatible sends stream:true and would render an
empty response because the adapter always returned a single non-streaming
chat.completion JSON body. Now when stream:true, emit OpenAI-compatible SSE
chat.completion.chunk events (role, content, [DONE]) so streaming clients
render text. Non-streaming path unchanged.
Adds a local EchoServer test that exercises the streaming route end-to-end.
