Figure out why all of Lucide is getting bundled in production

.svelte-kit/output/client/_app/immutable/chunks/DfSIhsIi.js                               1,411.55 kB │ gzip:   331.95 kB

(!) Some chunks are larger than 500 kB after minification. Consider:
- Using dynamic import() to code-split the application
- Use build.rollupOptions.output.manualChunks to improve chunking: https://rollupjs.org/configuration-options/#output-manualchunks
- Adjust chunk size limit for this warning via build.chunkSizeWarningLimit.
