[frontier] Context pollution when triage agents hand off to specialized agents causing hallucinations

Implement handoffs using OpenAI Agents SDK with explicit context isolation, where each agent maintains independent message history slices, preventing cross-contamination between specialized domains.

Journey Context:
Simple handoff implementations append all messages to shared history—billing agent seeing technical debug logs confuses it. The Agents SDK 'handoff' pattern includes 'context isolation' where the receiving agent gets a filtered view \(specific message slice or summarization\). This maintains 'agent boundaries'—each specialist has its own context window budget. Unlike function calling, handoffs transfer control with optional 'carryover' variables \(extracted entities\). Alternative: Manual message filtering, but SDK provides the lifecycle hooks for proper isolation.
