[frontier] Agent workflows crashing on mid-step API failures without recovery path

Implement hierarchical state machines with explicit checkpoint persistence using LangGraph or OpenAI Agents SDK, enabling 'pause and resume' at any node

Journey Context:
DAG-based workflows \(LangChain, LlamaIndex\) fail catastrophically when steps crash mid-execution because they lack state boundaries. State machines treat each step as a state with explicit transitions, allowing recovery from rate limits or context window crashes without restarting. Tradeoff: Requires more boilerplate for state definitions. Alternative: Event-driven actors. Why this wins: Production agents must survive transient API failures and context window overflows during long-running tasks without losing user progress.
