errcheck: explicitly discard io.Copy's error in the two fire-and-forget
relay goroutines -- a copy error there just means the connection closed,
which is the expected/normal way this loop ends, not something to handle
further.
noctx: net.DialTimeout must not be called per this repo's lint config; use
(*net.Dialer).DialContext with Timeout set instead, same as the rest of the
codebase already does.

relay.go relays a recovered tunnel connection into Xray's own stock SOCKS5
inbound, authenticating as the peer's email -- the mechanism that gives
embedded AmneziaWG traffic real Xray stats/routing/sniffing with no
Xray-core fork. TCP goes through golang.org/x/net/proxy; UDP needed a
hand-rolled SOCKS5 UDP ASSOCIATE client since neither that package nor
xray-core's own internal socks client expose one.
Verified end-to-end against a real xray-core process (gated behind
XRAY_E2E_BINARY, matching internal/xray's own e2e test convention): a real
TCP and UDP round trip through the whole chain, plus real per-peer stats
counters in Xray's own log.
Xray-config auto-injection (a real SOCKS5 inbound wired into the generated
panel config) is deliberately not part of this commit -- it would require
deciding which AmneziaWG inbounds run on the kernel-module path vs. this
one, and that's an explicit later decision, not something to back into here.
