[synthesis] State desynchronization in multi-agent handoffs

Include the exact return value of the last state-mutating tool call in the handoff payload, rather than just a natural language summary of the completed step.

Journey Context:
In multi-agent systems, agents hand off tasks by summarizing what they did. Agent B then tries to operate on the state, but fails because Agent A's tool call used a slightly different schema than intended, or failed silently. The natural language summary masked the actual state. The synthesis reveals that inter-agent communication via natural language summaries creates a lossy compression of state, leading to desynchronization. Treating tool outputs as ground truth state and passing them verbatim during handoffs prevents this lossy compression failure.
