Expected result

Linter does report or fix this useImportType rule if the file is named main.d.ts but if you rename to file to main.ts, it does report and fix it.

Code of Conduct

That's expected.

In a d.ts what you import is always considered a type, and even when there's a duplication, TypeScript always resolves the types, never the runtime
