func DiscoverPrivateIPv4() []string

DiscoverPrivateIPv4 walks every up, non-loopback interface and returns each IPv4 address that looks routable on a LAN. Only private-range addresses (RFC1918) are kept so a host with a public IP doesn't accidentally suggest exposing itself. Order is stable per interface enumeration; duplicates are deduped.
