Report #2217

[architecture] You cannot reconstruct which agent did what across a distributed workflow

Propagate W3C traceparent and baggage through every agent run, handoff, and tool call; tag each span with agent name and node so a single trace spans the whole chain.

Journey Context:
Agent frameworks may emit their own traces, but traces break at handoff or tool-call boundaries unless a common ID flows through. W3C Trace Context is the default propagation format in OpenTelemetry and is supported by most backends. Pass traceparent in message headers/context and use baggage for request-scoped metadata \(user id, tenant\). Without this, debugging a multi-agent failure means stitching together separate logs by timestamp.
