Part of #560.
Engine inserts a default Camera entity if the root-instantiated prefab tree contains no Camera component anywhere.
Rules:
- Only at root instantiation — the prefab loaded as a top-level via the state-binding entry point.
- Nested prefabs do not get a default camera. This prevents "two cameras when I nest a scene inside a scene."
- Explicit override stays available via a
Camera component on the root entity (or anywhere in the tree).
