agent: observability

When does this happen?

IF Open WebUI Langfuse filter pipeline adds a chat_id field to the request body if missing, causing models like GPT-4o to fail or return errors.

How others solved it

THEN Modify the pipeline's inlet method to stop injecting chat_id into the request body. Store chat_id internally for tracing purposes without forwarding it to the model. Apply the patch from open-webui/pipelines#388 which removes the chat_id injection.

# In pipeline inlet function, remove or comment out the injection:
# if 'chat_id' not in body:
#     body['chat_id'] = str(uuid.uuid4())
# Instead, keep chat_id in a separate metadata field.
