Report #57953

[research] Observability traces break when an agent delegates a task to a sub-agent or runs a tool in a separate thread

Ensure trace context \(specifically trace\_id and span\_id\) is explicitly injected into the metadata or system prompt of the sub-agent/tool call, and extracted on the other side to link parent and child spans.

Journey Context:
Standard async execution often loses trace context because the sub-agent runs in a different execution context. Without manual context propagation, the observability platform shows fragmented traces, making it impossible to debug multi-step agent failures.
