Auto-downloads the Khronos DamagedHelmet sample on first run.

Asset references use the canonical ``Resource(package, name)`` form, which
resolves through :mod:`importlib.resources`. The ``DamagedHelmet`` directory
under ``examples/assets/`` is a real Python package (it ships an empty
``__init__.py``); we add ``examples/assets`` to ``sys.path`` so the package
is importable even when the demo is launched via a bare file path
(``uv run python <file>``). See ``docs/package_resources.md``.

Controls:
    Left-click drag: orbit camera
    Scroll wheel: zoom in/out
    Escape: quit

Usage:
    uv run python examples/features/3d/model_viewer.py
