[frontier] Shared context in multi-agent swarms causes privacy leaks and context bloat between unrelated tasks

Use explicit handoffs: Agent A packages relevant state into a Handoff object, transfers control to Agent B with only necessary context, clearing previous window

Journey Context:
Early multi-agent systems shared a global message list. This causes agents to see private data from other users or unrelated tasks. The handoff pattern treats agents as state machines with explicit transitions, passing only filtered state. This is the pattern used in the OpenAI Agents SDK for privacy-preserving multi-agent workflows.
