- Add unicast_src_ip and unicast_peers config fields - NewUnicastSocket binds to source IP for proper packet reception - SendTo() sends VRRP advertisements directly to peer IPs - Receive loop filters packets from non-peer sources in unicast mode - Backward compatible: multicast mode used when unicast_peers is empty - Add unicast config example (etc/config.unicast.yaml) - Update README with unicast documentation and examples
