Fixed

• NetBSD UDP probes: Auto-detect source IP for UDP DGRAM sockets on NetBSD. Fixes "No route to host" (EHOSTUNREACH) when sending UDP probes without --source-ip (#47)
• NetBSD IPv4 PMTUD retry spam: PMTUD now terminates immediately on first DF flag failure instead of retrying every probe round. Prints a single warning when IP_DONTFRAG is unavailable (#47)

Three targeted fixes for the shutdown hang reported in #41:

• Bounded IPv6 echo drain loop — The poll_ipv6_echo_reply drain loop now caps at 256 packets per batch and checks the cancellation token, preventing starvation when the socket is continuously readable
• Ctrl+C force-exit handler — tokio::signal::ctrl_c() handler works outside cr...
