[frontier] How to prevent agent state corruption in complex multi-step workflows

Use LangGraph's Pydantic-based state validation to enforce schema constraints on graph state at every node transition, preventing invalid state shapes from propagating through the workflow.

Journey Context:
Dict-based state allows typos and missing keys to cascade through long workflows, causing failures at distant nodes that are hard to debug. LangGraph with Pydantic state models validates state at compile and runtime: nodes receive validated objects, state updates are type-checked. Essential for long-running agent workflows where state corruption is expensive to debug.
