SvelteKit's automatic SW registration also runs under `vite dev`, where
the worker intercepted/cached the dev-server e2e suite (42 failures).
Disable auto-registration (kit.serviceWorker.register: false) and
register the worker manually from the root layout guarded by `!dev`, so
`vite dev` and the e2e suite run worker-free while the production build —
and the PWA preview test — still install it.
