- Replace raw ICMP socket implementation with system ping command - Add regex-lite dependency for parsing ping output - Add tokio process feature for async command execution - Support macOS and Linux ping output formats - Add iputils to Dockerfile for setuid-root ping - Remove socket2 dependency (no longer needed) This eliminates the need for CAP_NET_RAW capability in containers.
