Story 2: Remove SvelteKitPWA Plugin Dependencies
- Remove @vite-pwa/sveltekit from package.json dependencies
- Remove SvelteKitPWA plugin import and configuration from vite.config.ts
- Clean up plugin configuration including manifest, workbox, and devOptions
- Build process now works without plugin (service worker migration needed next)
Dependencies reduced by 309 packages
Build fails on workbox imports as expected - ready for Story 3
