fix(closes OPEN-8223): enhance Google ADK tracing with improved user query handling and output management

Pull Request

Summary

Fix Google ADK tracer issue where traces showed "user_query": "Processing..." and "output": null when applications used early generator exit patterns (e.g., break on first final response).

Changes

• Fix timing bug in google_adk_tracer.py: Update step data immediately during generator iteration instead of after loop completion
• Add fallback logic: Preserve existing behavior for generators that complete naturally
• Maintain backward compatibility: Both early-exit and full-consumption patterns now work correctly

Modified Files:

• src/openlayer/lib/integrations/google_adk_tracer.py (lines 608-649)

Context

User reports of incomplete traces when using common async generator patterns:
async for event in agent.run_async(...):
if event.is_final_response():
response = event.content.parts[0].text
break # ← This broke tracingRoot cause: Step updates happened after async for loop, but break prevented loop completion, so updates never occurred.

Testing

• Unit tests:
• Manual testing: Verified with multi-agent customer support system in fastapi-agui-example/
• Trace verification: Confirmed correct data appears in Openlayer dashboard
• Backward compatibility: Original usage patterns still work

can you clean the outputs of all cells of the notebook?

[viniciusdsmello]

Done!

[gustavocidornelas]

lgtm! just need to clean the output of all cells of the Jupyter notebook. Once done, we can merge
