[research] Observability breaks during agent-to-agent handoffs losing trace context

Propagate OpenTelemetry trace and span IDs in the metadata of the handoff payload. Ensure the receiving agent initializes its telemetry provider as a child span of the invoking agent.

Journey Context:
When Agent A delegates to Agent B, standard logging often treats B as a new root request. This fragments traces, making it impossible to debug the full lifecycle of a user request. By explicitly passing trace\_id and parent\_span\_id in the handoff message, you stitch the distributed trace together. The alternative—correlating logs via timestamps—is fragile and unscalable in concurrent environments.
