Research direction

The issue is about increasing the default `build.chunkSizeWarningLimit` for the `@storybook/vue3 vite` package. The relevant file is likely `packages/builder vite/src/optimized/vite config.ts` or similar within the storybook repo. The user has provided a temporary fix using `viteFinal`. A contributor should locate where the default Vite configuration is set for the vue3 vite builder and add `chunkSizeWarningLimit: 800` to the `build` options. Additionally, check if there's a constant for this value elsewhere in the codebase.
