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.

New internal/amneziawgnet package: builds a real amneziawg-go Device over a
gVisor netstack from an existing amneziawg.Instance, with a TCP/UDP
forwarder that recovers each tunnel connection's real destination and a
peer-identity index keyed by AllowedIPs. This is the foundation for
migrating AmneziaWG off the kernel-module+TPROXY path (see the AmneziaWG-go
vs kernel-module decision) -- nothing wires into live traffic yet, that's
Phase 2 (relay into Xray's own SOCKS5 inbound).
Covered by three real end-to-end tests: a genuine handshake + TCP forwarder
+ identity resolution, the same for UDP (including a reply routed back
through the tunnel), and the manager's reconfigure-in-place vs. rebuild
lifecycle.
