Stateful NPC

Attach StatefulNpcExample and AstralRuntimeInitializer to a GameObject. Call Ask from a UI button or gameplay interaction. The default mock backend covers agent lifecycle, history ownership, cancellation, and tool-call parsing without an external model.

The component keeps system prompt, summary, and retrieved memory context in the native agent. It saves history under Application.persistentDataPath, restores that history on the next run, and releases the assigned executor slot after a chat finishes. The move_to tool demonstrates how generated structured actions cross into gameplay code.

Use ClearHistory when starting a new save game. For real dialogue, set the model path and backend and replace the log calls with your subtitle and action dispatch systems.
