Align _Color with _BaseColor for Skin, Suit and Tongue materials to fix color mismatches. Also update Git LFS object IDs for SampleScene, PC_RPAsset.asset, ProjectSettings.asset and QualitySettings.asset (assets were re-saved, resulting in new OIDs and size changes).
Add a full Unity project scaffold: Input System actions (.inputactions + meta), SampleScene and scene meta, URP render pipeline and profile assets, TutorialInfo (scripts/icons), a Readme LFS pointer, ProjectSettings (audio, graphics, input, quality, XR, etc.), and Packages/manifest.json. Sets up default player and UI input mappings, rendering settings, and editor/project configuration for the project.
