What's the optimistic mutations rollback pattern?

// package.json - Drop-in replacement
{
  "overrides": {
    "vite": "npm:rolldown-vite@latest"
  }
}

// vite.config.ts - Advanced Vapor optimization
import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'

export default defineConfig({
  plugins: [vue()],
  build: {
    rollupOptions: {
      output: {
        format: 'es',
        advancedChunks: {
          groups: [
            { name: 'vue-vapor', test: /vue.*vapor/ },
            { name: 'vendor', test: /react|lodash/ }
          ]
        }
      }
    },
    target: 'es2022'  // WASM signal output
  }
})
