Add Nebula Browser app, UI and assets

Add initial Nebula Browser project skeleton: CMakeLists to configure and link CEF (including post-build steps to copy runtime and UI files), a Windows CEF-based entry (app/main.cpp) that initializes CEF and loads the bundled UI, and a full ui/ and assets/ tree (HTML, CSS, JS, fonts, icons, and branding images). Update .gitignore to ignore build/out, thirdparty/cef, IDE and common OS artifacts.
