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.
Add common binary/asset patterns to .gitattributes to route large or binary files (.psd, .fbx, .obj, .png, .jpg, .asset) through Git LFS. Extend .gitignore to exclude common OS-generated files (.DS_Store, .Spotlight-V100, .Trashes, ehthumbs.db, Thumbs.db, etc.) to prevent committing platform artifacts.
