Unifies IPv4 and IPv6 default route queries under a shared result structure and per-family functions. Improves clarity and extensibility by centralizing route logic, streamlining detection of preferred interfaces, and updating all consumers to use the new API. Prepares for more robust multi-protocol network information handling.
