[frontier] Multi-agent workflows hitting dead-ends or infinite loops in DAG-based orchestration

Adopt cyclic graph topologies with deterministic checkpoint validation allowing agents to revisit nodes with new context

Journey Context:
Early multi-agent systems forced DAG structures to avoid infinite loops, but this prevents iterative refinement where Agent A must re-evaluate Agent B's output. Modern production systems use cyclic graphs with Pregel-style checkpointing: each node execution is checkpointed, and cycles are permitted only if context has meaningfully changed \(validated via semantic hashing\). This enables recursive critique patterns while preventing infinite loops through idempotency checks.
