[frontier] Distributed multi-agent systems lose causal relationships across service boundaries

Use OpenTelemetry context propagation \(Baggage and SpanContext\) to inject agent IDs, conversation context, and causal chains into HTTP headers or message metadata, enabling distributed tracing of agent reasoning

Journey Context:
In microservice-based agents \(planning-agent calls research-agent via HTTP\), standard logs lose the causal link between cause and effect. The 2025 frontier pattern treats agent systems as OTel-native: agents propagate context using W3C TraceContext and Baggage. Implementation: the root agent creates a Span; before HTTP calls, it injects \`traceparent\` and \`baggage\` \(containing \`agent\_id\`, \`session\_id\`, \`conversation\_context\`\) into headers. Downstream agents extract this to continue the trace. This enables 'distributed agent debugging'—seeing the full causal chain of a decision across process boundaries.
