Report #67632

[frontier] Agent stuck in infinite loops or losing state between steps

Replace while-loop agent patterns with explicit StateGraph nodes and conditional edges; persist state between transitions

Journey Context:
Naive agents use while-true loops with memory that grows unbounded and cannot recover from crashes. State machines force explicit transition logic, enable checkpoint/resume, and make agent behavior deterministic and testable. The tradeoff is initial complexity, but production systems require observability that only state graphs provide.
