Update CI to build Rust binaries and clarify Node.js builds

- Rename Node.js job to clarify it builds both frontend and backend
- Add comment explaining what npm run build does (CSS, client, server)
- Include public/bundle/ in Node.js artifacts for frontend assets
- Add Rust binary build job with matrix strategy for multiple platforms:
  - Linux (x86_64)
  - macOS (x86_64 and arm64)
  - Windows (x86_64)
- Cache Rust dependencies for faster builds
- Run tests only on native platforms (not cross-compilation targets)
