MultiMeshInstance3D Demo — 1600 cubes rendered via instancing.

Demonstrates mass instancing of identical meshes using MultiMeshInstance3D.
1600 cubes are laid out as a ground-level field on the XZ plane with slight
sine-wave height variation and random rotation for visual variety. Rendered
with a single shared material, camera orbits from above.

Run:  uv run python packages/graphics/examples/3d_multimesh.py
Test: uv run python packages/graphics/examples/3d_multimesh.py --test

Controls:
    Mouse drag  - Orbit camera
    Scroll      - Zoom in/out
    R           - Reset camera
