Advanced AI Prompt for Manual Chunking Strategy in Vite

Act as a Senior Build Performance Engineer. Design a sophisticated Vite manual chunking strategy for a massive React application utilizing the `build.rollupOptions.output.manualChunks` configuration. The primary objective is to aggressively isolate heavy, rarely-changing vendor libraries like [VENDOR_LIBS] into dedicated, long-term cacheable bundles, while strictly ensuring no single JavaScript chunk exceeds a [MAX_CHUNK_SIZE] threshold (e.g., 500kb). Provide the exact `vite.config.ts` TypeScript code snippet utilizing a functional chunking approach. Include a highly technical explanation detailing how this specific module-splitting strategy prevents the catastrophic, unnecessary cache invalidation of stable vendor code whenever internal application business logic is updated, thereby drastically improving subsequent page load times and Core Web Vitals.
