Subject: [PATCH] build: drop vitePreprocess from the shared Svelte config

svelte-check and the Vitest Svelte plugin load svelte.config.mjs, and its
vitePreprocess() import pulls in Vite on every svelte-check run. The
production build never reads this file and compiles every component
without a preprocessor, so no component depends on one. Without it,
svelte-check and Vitest compile components the way the bundle does.
