Wayfinder generates invalid TS when namespace repeats (e.g. Prism/Prism), causing duplicate identifier in barrel index.ts

Description

When a controller namespace segment repeats (e.g. App\Http\Controllers\Prism\Prism\Http\Controllers...), the generated barrel file resources/js/actions/Prism/index.ts contains an import and a const with the same
identifier:

  import Prism from './Prism'

  const Prism = {
      Prism: Object.assign(Prism, Prism),
  }

  export default Prism

This causes TypeScript errors:

• TS2440: Import declaration conflicts with local declaration of 'Prism'
• TS7022: 'Prism' implicitly has type 'any' because it does not have a type annotation and is referenced directly or indirectly in its own initializer.
• TS2448: Block-scoped variable 'Prism' used before its declaration.

Steps To Reproduce

1. Create controllers under a repeated namespace path, e.g. App\Http\Controllers\Prism\Prism\Http\Controllers\PrismChatController.

2. Ensure routes point to those controllers.

3. Run:

   php artisan wayfinder:generate --path=resources/js --with-form

4. Open resources/js/actions/Prism/index.ts.

Expected Behavior
Generated barrel file should use distinct identifiers (or safe aliases) so that import and const names don’t collide.

Actual Behavior
Generated index.ts contains import Prism and const Prism = { ... }, causing TS errors and breaking pnpm run types.

Additional Context / Suggestion
The issue seems to come from barrel generation using the same safeMethod name for both import alias and the exported const. A simple fix could be to disambiguate the top-level export variable name when it matches a child
import (e.g. PrismNamespace or PrismRoot), or apply TypeScript::safeMethod differently for the exported const.
