[frontier] Multi-agent swarms exceed context limits when passing full conversation history between agents

Implement handoff protocols that pass only distilled 'agent cards' and delta-context using OpenAI Swarm's \`context\_variables\` pattern

Journey Context:
Naive multi-agent implementations pass entire chat histories, hitting token limits quickly. The emerging pattern treats handoffs as function calls that transfer only necessary context—compressed task state, not full conversation. This uses structured context variables rather than message lists. OpenAI Swarm demonstrates this by passing only explicit context\_variables between agents, effectively treating agents as stateless functions with injected context rather than maintaining persistent chat sessions.
