Exclude Capacitor native-only plugins from Vite dep optimization

@capacitor/filesystem and @capacitor/share are dynamically imported
behind a Capacitor.isNativePlatform() guard, but Vite's import analysis
plugin still tries to resolve them at transform time in dev mode. This
causes a 'Failed to resolve import' error when running the dev server.

Excluding them from optimizeDeps prevents Vite from pre-bundling these
packages, letting the dynamic imports resolve naturally at runtime.
