Fix v2 assets missing from distributions

[dev2703]

Summary

• add the four targeted package-data patterns required by the v2 model layout
• add a wheel-level regression test that compares packaged model data with the source tree, installs the wheel outside the checkout, and resets both v1 and v2 environments
• run the existing suite and wheel smoke test on pull requests

Closes #3.

Reproduction and verification

Before this change, a clean wheel install omitted 96 v2 files and OrcaHandRight(version=\"v2\").reset() failed while loading models/v2/assets/scene.xml.

After this change:

• all 342 source .xml, .mjcf, and .stl data files are present in both the wheel and sdist (0 missing)
• the newly covered v2 layout contributes the expected 96 files: 90 meshes, 4 XML files, and 2 MJCF files
• clean wheel-installed OrcaHandRight environments reset successfully for both version=\"v1\" and version=\"v2\"
• the full test suite passes (32 tests)

Downstream impact

orca_teleop exposes orca_sim from main through its optional sim dependency. The missing wheel assets make its v2 simulation sink unusable from a clean install; restoring distribution integrity unblocks that path.

This change validates packaged simulation only. It does not claim teleoperation or physical hardware validation.

Test plan

• python -m pytest
• python -m build
• inspect wheel and sdist model-data coverage
• install the wheel in a clean virtual environment outside the source tree
• reset v1 and v2 right-hand environments from the installed wheel
