[frontier] LangGraph agent getting stuck in infinite loops or non-deterministic execution paths

Replace while-loop agent execution with explicit StateGraph where LLM only decides transitions between fixed states, not open-ended 'act' steps. Define states as typed Pydantic objects and edges as conditional routing functions using LangGraph's StateGraph.

Journey Context:
Teams start with 'agent loops' \(plan->act->observe\) but hit non-determinism and debugging hell. State machines force explicit contract: LLM outputs must fit transition schema, not arbitrary JSON. Tradeoff: less 'flexibility' but massive gains in testability, observability, and replayability. LangGraph's StateGraph is becoming the default over ReactAgent patterns for production reliability.
