LGTM. Few suggestions to improve:

• We shall fix core issues (components/store) and start showing a warning when this fallback is auto injected
• We might improve mlly to detect named export with default as type: default

This fix works for you ?

On my machine

const exports = findExports(code);
console.log(exports);

gives me :

...
[
  {
    type: 'named',
    exports: ' PiniaNuxtPlugin as default ',
    code: 'export { PiniaNuxtPlugin as default }',
    start: 841,
    end: 878,
    names: [
      'default'
    ]
  }
]
[
  {
    type: 'named',
    exports: ' PiniaNuxtPlugin as default ',
    code: 'export { PiniaNuxtPlugin as default }',
    start: 841,
    end: 878,
    names: [
      'default'
    ]
  }
]

so i.type === "default" || i.name === "default" is always false, and the error persist

[SSR] Error transforming defaultexport:[...]/node_modules/@pinia/nuxt/dist/plugin.mjs: Error: Parse failure: Duplicate export 'default' (36:7)
Contents of line 36: export default () => {}

looking at mlly, NamedExport only has names

export interface NamedExport extends ESMExport {
  type: 'named'
  exports: string
  names: string[]
}
