Add TCP/UDP forward handler e2e tests covering basic forwarding, alias (forward/tcp), sniffing, raw pipe, idleTimeout, multi-node protocol filtering, sniffing bypass (403), stateful UDP, and stateless UDP. New files: - forward_test.go: ForwardSuite with 9 test methods - testdata/forward/: server configs (tcp, udp, stateless, sniffing, bypass, multi-node, idleTimeout) - scripts/tcp_idle_timeout.py, udp_forward_test.py: Python harnesses for in-container idle timeout and UDP echo verification
