…c#1651) OpenaiResponsesStreamState.get_attributes() did not extract usage (input_tokens, output_tokens) from the response, so gen_ai.usage.* span attributes were missing for streaming Responses API calls. Add the same usage extraction used in non-streaming paths.

Closes #1651
Summary
When using the OpenAI Responses API with streaming (
client.responses.stream()), logfire did not capture token usage attributes (gen_ai.usage.input_tokens,gen_ai.usage.output_tokens) on the span. Non-streaming calls worked correctly.Change
OpenaiResponsesStreamState.get_attributes()now extractsusagefrom the response and setsINPUT_TOKENSandOUTPUT_TOKENSon the span, matching the non-streaming path and the pattern used inon_response()(lines 298–304).
