[research] Multi-agent system fails but final output eval cannot pinpoint which agent handoff failed

Instrument distributed tracing with specific span attributes for handoff.from, handoff.to, and handoff.context. Write evals specifically targeting the context completeness at the moment of handoff.

Journey Context:
Evaluating only the final output of an agent chain makes debugging impossible—if the last agent fails, you don't know if it was its own fault or if the previous agent passed insufficient context. Treating handoffs as explicit spans allows you to run regression evals on the routing and context passing independently of the downstream execution.
