Repro Code

const A = 0;
export type A = typeof A;

ESLint Config

module.exports = {
  parser: "@typescript-eslint/parser",
  {
   "rules": {
    "no-unused-vars": "off",
    "@typescript-eslint/no-unused-vars": "error"
    }
  }
};

tsconfig

{
  "compilerOptions": {
    // ...
  }
}

Expected Result

Should report an error same as https://typescript-eslint.io/play/#ts=5.7.2&fileType=.ts&code=MYewdgzgLgBAgjAvDADAbgFAagTwA4Cm8SMuhIAZvGkA&eslintrc=N4KABGBEBOCuA2BTAzpAXGUEKQHYHsBaWXWZRAE0IDcBDaVDSfAMxcgBpxtIABAFwCeABxQBjaAEth-QiniTc-APQFipclToN0URNGj5okbgF8QpoA&tsconfig=N4KABGBEDGD2C2AHAlgGwKYCcDyiAuysAdgM6QBcYoEEkJemy0eAcgK6qoDCAFutAGsylBm3TgwAXxCSgA&tokens=false

The difference is type A was not exported, so I suspect it is due to const A and type A having the same name, it was mistakenly assumed that const A had also been exported, so no error was reported.

const A = 0;
++ type A = typeof A;
-- export type A = typeof A; 

Actual Result

No error reported
