tcp: extend TcpInfo with send/recv queue, congestion window, MSS
TCP_INFO socket option now returns real-time connection metrics:
- tcpi_snd_queuelen: bytes queued for transmission
- tcpi_rcv_queuelen: bytes waiting in receive buffer
- tcpi_snd_cwnd: send capacity (congestion window proxy)
- tcpi_rcv_wnd: receive capacity (advertised window proxy)
- tcpi_snd_mss: maximum segment size (1460 for Ethernet)
- tcpi_state, tcpi_rto preserved from prior version
Struct layout: #[repr(C)] 28 bytes, compatible with Linux TCP_INFO consumers.
