[frontier] Static agent graphs force simple tasks through complex decision nodes wasting tokens and adding latency

Implement dynamic graph rewriting where parent agents spawn ephemeral sub-graphs \(sub-agents\) at runtime using LangGraph's \`Send\` API or Swarm dynamic handoffs, executing them with context-specific topologies, then merging results back.

Journey Context:
Static graphs \(like early LangGraph\) force all tasks through the same review and decision nodes, wasting tokens on irrelevant checks. Dynamic rewriting allows 'just-in-time' agent topology—simple tasks bypass review nodes, complex tasks spawn verification sub-agents. This pattern is emerging in 2025 as teams move from demo graphs to production adaptive systems that optimize token usage based on real-time task complexity.
