Done! I've removed all unnecessary changes and now only these minimal files are modified following the PR #569 pattern:

1. NewArch/package.json - React Native version updates only (0.79.x → 0.80.x)
2. NewArch/windows/NewArch.Package/Package.appxmanifest - version increment (1.0.5.0 → 1.0.6.0)
3. NewArch/windows/NewArch/NewArch.vcxproj - comment update to reference 0.80.0-preview.1

No image changes or other unnecessary project files. ESLint passes with only the pre-existing 187 style warnings.
