afpacket socket is only available on linux

Error message

afpacket socket is only available on linux

What it means

Platform stub: on non-Linux (or arm64/darwin builds per the build tag) capture.NewSocket has no AF_PACKET implementation, so any attempt to use the sock_raw listener gets this sentinel error instead of a socket.

Solutions

1. Run on Linux x86_64 where the real AF_PACKET socket implementation is compiled in
2. Use the pcap-based listener instead of --input-raw-worker/sock_raw on unsupported platforms
3. Switch capture engine if the build tag excluded sock_raw
