TypeScript plugin reports false errors for test files in standalone mode

[hanna-skryl]

What happened?

When running the TypeScript plugin in standalone mode, test files produce misleading semantic errors like Cannot find name 'describe'. or Cannot find name 'expect'.

This resulted in 2581 semantic errors across all test files in the workspace.

The TypeScript plugin in standalone mode uses tsconfig.base.json directly, which doesn't include vitest/globals in its types. Project-level tsconfig.test.json files do have the correct types configured, but the plugin never sees them.

What would you expect to happen?

Test files should be analyzed with their proper type definitions, or excluded from analysis.

What steps did you take?

1. Ran npx nx run workspace:code-pushup --onlyPlugins=typescript
2. The TypeScript plugin used tsconfig.base.json as configured in the preset
3. Test files were analyzed without Vitest type definitions
