Use QRegularExpression behind the same Qt version guard as totalMemoryBytes() in availableMemoryBytes(), where a bare QRegExp broke every Qt6 Linux build. hasAtLeastGiB() now treats a 0 reading (unsupported platform or failed query) as unknown and skips the low-memory prompt instead of misreading it as low memory.
