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 VS Code workspace/launch/settings for Unity development and a new MainMenu scene/UI (uxml, uss, tss) with MainMenuController and related assets. Import two alien character FBX models (with generated .meta settings) and add folder metadata. Update Git LFS pointers for a Game Kit scene and add modifications to Game Kit Controller assets (World Canvas material and Save Camera render texture) and ProjectSettings/QualitySettings. These changes bring initial UI/menu assets and character models into the project and add editor tooling/config for easier development.
Add a new Pause Menu UI (UXML, USS, TSS, asset/meta) and related UI folder metadata. Add new terrain assets and TerrainData files, plus lighting settings for the 2.5d demo scene. Import a new character model (X Bot.fbx) with its importer meta and new characters folder. Update SampleScene and LFS pointers, and refresh render pipeline settings (Mobile RP & URP global settings) and project/package settings. Tweak multiple material files: align _Color with BaseColor, add SHADOWCASTER to disabled shader passes for Ellen materials, and assign a missing main texture for Vincent_Hero_High_diffuse.
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.
