> Problem
> TopologyTestDriver cannot access or test headers-aware state stores (TimestampedKeyValueStoreWithHeaders and TimestampedWindowStoreWithHeaders). When users add these stores to their topology
>   and try to access them in tests using existing methods like getKeyValueStore() or getTimestampedKeyValueStore(), they encounter issues:
>   1. No method to retrieve the raw headers-aware store (with headers access)
>   2. Existing getter methods don't recognize headers-aware stores
>   3. Tests cannot write test data or assert on values from headers-aware stores
>   4. No way to verify header-related functionality in tests
