Function getRefreshToken

getRefreshToken(): null | string
Gets the current refresh token

Delegates to the token-operations module's getRefreshToken function, preserving the same function signature for backward compatibility.

Returns null | string
Current refresh token or null if not authenticated
Example
```
// Get refresh token
import { getRefreshToken } from "./auth/storage/token-store";

const refreshToken = getRefreshToken();
console.log("Has refresh token:", !!refreshToken);
```
Deprecated
Use getRefreshToken from token-operations directly
Source
```
export function getRefreshToken(): string | null {
  return getRefreshTokenOp();
}
```
