[frontier] Multi-agent handoffs lose critical context causing repetitive work or errors when passing tasks between agents

Implement structured state transfer protocol for swarm handoffs: serialize agent state \(scratchpad, findings, intent\) into a schema, pass via context\_variables, and validate on receipt rather than passing raw chat history

Journey Context:
Early multi-agent systems pass only conversation history between agents, losing the internal monologue, tool results, and structured understanding of the previous agent. The frontier pattern treats handoffs as 'process migration': when agent A hands to agent B, it packages its 'mental state'—key-value pairs of what it learned, the current plan, and user intent—into a Pydantic model in context\_variables, not just raw text. This structured handoff prevents 'context dilution' where the new agent wastes tokens re-learning what the previous agent knew. This enables emergent workflows where a research agent dynamically spawns a code-writing agent mid-task without pre-defined graphs.
