[research] Multi-agent handoffs drop context or loop infinitely without triggering errors

Instrument handoffs as distinct spans with attributes for the sender, receiver, and passed state. Set trace-level limits \(e.g., max 5 handoffs\) and write evals specifically checking for circular handoff patterns.

Journey Context:
In multi-agent systems, agents passing tasks back and forth can get stuck in infinite loops or lose critical context. Standard tracing just shows a long trace. You need to explicitly model the handoff as an event, evaluate the context diff at each step, and fail the trace if handoff depth exceeds a threshold.
