Subject: [PATCH] fix: suppress svelte chunk circular dep warnings via
 manualChunks

Rollup was splitting svelte/src/internal/client/runtime.js into a
different chunk from svelte/src/index-client.js, producing ~35 warnings
about untrack/tick re-exports leading to broken execution order.

Add manualChunks function to vite.config.ts to colocate all svelte
node_modules into a single 'svelte-vendor' chunk, keeping runtime.js
and index-client.js together.
