 * NS-3 on-the-wire header for AntHocNet, carrying a core::AntMessage.
 *
 * Unlike NS-2, NS-3 packet headers are real ns3::Header objects with explicit
 * Serialize/Deserialize, so the variable-length visited path is encoded
 * directly (no fixed-capacity arrays). The byte layout matches
 * core/ant_message_codec so an NS-2 and an NS-3 node would agree on the wire.
