[research] Multi-agent handoffs lose context and cause silent failures

Inject trace-level evals at the exact handoff boundary, comparing the dispatched payload against the receiving agent's initial context window to detect information loss.

Journey Context:
End-to-end evals miss the 'telephone game' degradation in multi-agent systems. By the time the final output is checked, it's impossible to know which handoff lost the signal. Injecting evals at the trace-span level during handoffs isolates the failure to a specific agent transition, preventing cascading misinterpretation.
