[frontier] Agent context lost when transferring between specialized sub-agents

Serialize full \`context\_variables\` and \`messages\` history into the Swarm \`handoff\` function rather than passing only the last message

Journey Context:
Simple agent handoffs pass only the latest user query, causing the receiving agent to lose all previous context, system instructions, and tool results. The Swarm pattern defines a \`handoff\` where you explicitly pass \`context\_variables\` \(shared state\) and the full \`messages\` array. This enables true stateful multi-agent workflows where Agent B can see Agent A's tool calls and observations. Alternatives like resetting context on handoff lead to repetitive tool calls and lost user preferences. The explicit transfer is crucial for building composable agent teams.
