Implements Python-side room graph data structures for LLM agent environments:
- Room, Door, WorldObject dataclasses with full metadata
- WorldGraph class with spatial queries (room_at, get_exits)
- Deterministic text generation (describe_room, describe_exits)
- Available action enumeration based on room state
- Factory functions for test scenarios (two_room, button_door)
Example output:
"You are in the guard room. The air is musty. On the ground you see
a brass key. Exits: east (the armory)."
