Commit Message

feat: net-stats feature — driver-level TCP/UDP + DNS counters

Gated behind net-stats (off by default, zero cost when unused). The WINC runs
the TCP/IP stack on-chip so the host can't see L2 frames — but the driver sees
every socket send/receive, so count them there.

- Process-global atomic counters incremented in the TCP send/receive, UDP
  send/receive, and DNS-query paths, on success only.
- NetStats { tcp/udp _tx/_rx _bytes/_ops, dns_queries }.
- WincClient::net_stats()/reset_net_stats() methods PLUS free wincwifi::
  net_stats()/reset_net_stats() that read without borrowing the client (needed
  when it's borrowed elsewhere, e.g. by a TLS stream).

Honest semantics (documented): app-layer TCP/UDP payload, not L2; *_ops are
socket calls, not wire packets.
