Report #9586

[research] Observability logs for agents are unreadable trees of JSON

Instrument agents with OpenTelemetry spans where each tool call is a child span of the agent's reasoning step, and attach the LLM's structured output as span attributes.

Journey Context:
Standard logging dumps unstructured text, making it impossible to reconstruct the agent's decision tree. Using OTEL spans with parent-child relationships mirrors the agent's actual execution graph. Attaching the structured tool I/O as span attributes allows observability backends to filter and search agent runs by specific tool failures.
