npm/cli#4828 caused package-lock.json to prune platform variants
not matching the local OS. Regenerated from scratch so Windows CI
gets @tauri-apps/cli-win32-x64-msvc and lightningcss-win32-x64-msvc.
Removed the lightningcss Windows install workaround from desktop
workflow. Removed deprecated asyncRequireModulePath from metro config.

Add x86_64-apple-darwin Rust target alongside the existing aarch64 target
and switch Tauri build to --target universal-apple-darwin, producing a single
DMG that runs natively on both Apple Silicon and Intel Macs.
