🙂 Expected behavior

No error

unplugin-auto-import has a broken export map. Their export map defines all their entrypoints as cjs only - they need a nested types entry for both the require and import conditions that points a different files with the correct module format. This is exactly the format confusion issue that arises when you use an incomplete export map.

Instead of

    "./vite": {
      "types": "./dist/vite.d.ts",
      "require": "./dist/vite.js",
      "import": "./dist/vite.mjs"
    },

it should be

    "./vite": {
      "require": { "types": "./dist/vite.d.ts", "default": "./dist/vite.js" },
      "import": { "types": "./dist/vite.d.mts", "default": "./dist/vite.mjs" }
    },

and, naturally, vite.d.mts needs to exist (it can just reexport stuff from vite.d.ts, though!).
