Stabilize PR workflow by aligning Vite resolution, updating UI chunk config, and fixing root test runtime deps

[Copilot]

Recent dependency updates introduced workflow instability: preview/build jobs failed from mixed Vite resolution, and full repo test execution failed from jsdom resolution in root turbo context. This PR tightens dependency/runtime consistency across the monorepo and updates UI bundling config to match Vite 8 behavior.

• Build/runtime dependency alignment

  • Forced a single Vite version across workspaces via root override (vite: 8.0.2) to prevent mixed Vite 7/8 resolution with @vitejs/plugin-react@6.
  • Updated lockfile accordingly.

• UI bundling compatibility with Vite 8 (rolldown)

  • Replaced object-style manualChunks with function-style chunk routing in /packages/ui/vite.config.ts.
  • Added normalized path matching and shared package matcher to keep chunk assignment deterministic.

• Monorepo test execution fix

  • Added jsdom to root devDependencies so root-level turbo run test can resolve Vitest’s jsdom environment consistently (not only from packages/ui scope).

// packages/ui/vite.config.ts
manualChunks(id) {
  const normalizedId = id.replaceAll('\\', '/');
  const isNodeModulePackage = (pkgName: string) =>
    normalizedId.includes(`/node_modules/${pkgName}/`) ||
    normalizedId.endsWith(`/node_modules/${pkgName}`);

  if (['react', 'react-dom', 'react-router-dom'].some(isNodeModulePackage)) {
    return 'react-vendor';
  }
  if (isNodeModulePackage('flexsearch')) return 'search';
}
