Issue Description
In a project configured with"composite": true and installed with pnpm, TypeScript flags error TS2742 in this minimaleslint.config.mjs.
//@ts-checkimporttseslintfrom"typescript-eslint";exportdefaulttseslint.config(tseslint.configs.recommended);
eslint.config.mjs:3:1 - error TS2742: The inferred type of 'default' cannot be named without a reference to '.pnpm/@typescript-eslint+utils@8.25.0_eslint@9.21.0_typescript@5.7.3/node_modules/@typescript-eslint/utils/ts-eslint'. This is likely not portable. A type annotation is necessary.
Fulltsconfig.json:
{"compilerOptions": {"allowJs":true,"composite":true,"module":"nodenext","noEmit":true,"strict":true }}The error is not shown without"composite": true, nor is it shown when using npm instead of pnpm.
