VR pet: model sources in the repo

The Toon Cat (sources/toon-cat/), the Tuxedo Cat glTF (sources/tuxedo-cat/)
and the Quaternius Shiba Inu and Fox (models/{shiba,fox}/model.glb), each
byte-identical to the previously fetched file and with a LICENSE.md
(author, original URL, licence, changes). The build no longer downloads
them; three.js (preview only) still comes from npm. The baked frames,
model dirs and icons are unchanged.
