[synthesis] Receiving agent re-explores dead ends because handoff only includes conclusions, not rejected alternatives

Structure inter-agent handoff payloads to include an explicit \`rejected\_approaches\` array alongside the \`current\_state\`, forcing the sending agent to articulate why other paths failed.

Journey Context:
When Agent A hands off to Agent B, standard practice is to pass the current state and the goal. However, Agent B lacks the history of \*why\* certain states were reached. Without knowing what was tried and failed, Agent B will often re-attempt the exact same dead ends. The synthesis is that context transfer must include negative knowledge. The tradeoff is increased token usage in the handoff, but it prevents infinite loops and duplicated effort in multi-agent systems.
