Report #57163

[architecture] Missing distributed tracing context across agent boundaries

Propagate W3C Trace Context \(traceparent and tracestate headers\) mandatorily across all inter-agent RPC, including baggage for business context \(e.g., user\_id, session\_id\), ensuring every log and span carries the full causality chain.

Journey Context:
Without correlation IDs, debugging multi-agent chains is guesswork; each agent appears as a black box. Teams often rely on timestamps which fail under clock skew or high concurrency. W3C Trace Context is the industry standard \(supported by Jaeger, Zipkin, OpenTelemetry\), ensuring interoperability. The tradeoff is payload overhead \(tens of bytes per request\) versus observability. Implementing this at the transport layer \(HTTP/gRPC middleware\) ensures agents cannot 'forget' to propagate.
