[research] Multi-agent system produces correct final answer but takes redundant loops or drops context during handoffs

Implement step-wise trace evals that score agent handoffs on context preservation and tool selection accuracy, not just final task completion.

Journey Context:
If you only eval the final output, agents can loop 5 times, call redundant tools, and lose critical context before accidentally getting the right answer. This costs a fortune in token usage and latency, and fails on slightly harder tasks. You must eval the intermediate traces, specifically the handoff events, to ensure the receiving agent gets exactly the context it needs without bloat.
