evgeny	f47ad7d87f	tcp_proxy: fix throughput (tx_queue backpressure) + connect timeout + integration test - Router: unified service delivery format [svc_id][src][dst][payload] (end-to-end src/dst from SVC_ROUTE header) - tcp_proxy_client: replace single tx_buf drop-on-backpressure with bounded tx_queue + send_q waiter + retry timer (no data loss, bulk window reopen — removes 62.5ms delayed-ACK stall) - tcp_io: configurable connect timeout (tcp_conn_set_connect_timeout) - tcp_proxy_server: connect_timeout config option (ms, default 2000, 0=off) - check.sh: run tcp_proxy_full integration test with sudo (skip if passwordless sudo unavailable) - test_tcp_io: connect timeout unit test; docs (lwip_nuances.md)	4 weeks ago
