[frontier] Ad-hoc agent delegation causes context loss and silent failures in multi-agent workflows

Implement schema-validated handoff protocols where the delegating agent packages reasoning traces, confidence scores, and rollback checkpoints into a validated HandoffCard object passed via function calling

Journey Context:
Simple message-passing between agents \(e.g., 'You handle this'\) loses critical context like the original intent, uncertainty estimates, and alternative paths considered. Production systems now use explicit handoff functions \(like OpenAI Swarm's handoff pattern\) with structured data: the handing agent fills a Pydantic model with task context, reasoning chain, confidence level, and explicit 'abort conditions.' The receiving agent validates this schema before acceptance. This prevents the 'telephone game' effect and enables precise rollback if the sub-agent fails. It adds overhead but is essential for reliability in hierarchical agent systems \(manager-worker patterns\).
