fix: proxy ERROR loop, BBR test backpressure, O(1) u_free, test ordering
- tcp_proxy: ERROR silently dropped (no ERROR->ERROR loop), Russian removed from logs
- etcp_bbr: swap min(lo) and max(4*mss) in bbr_bound_cwnd_for_inflight_model
- test_etcp_bbr: fix cwnd comparison (packets vs bytes)
- ll_queue: double-put detection (abort), Floyd cycle detection in consistency check
- ll_queue: QUEUE_DEBUG commented out (was always-on, O(N) per put)
- mem: u_free_impl now O(1) via doubly-linked list, double-free detection
- bbr_integration: queue_waiter_wait + call_soon backpressure (threshold=1)
- tests/Makefile.am: fast tests first, *.log cleanup before run

congestion: заменить AIMD на BBR v3 (per-link), добавить юнит-тесты BBR
- Новые файлы: src/etcp_bbr.h/c — полный порт BBR v3 из BBR/bbr_v3.c (референс сохранён)
- struct ETCP_LINK: удалены AIMD-поля (rtt_history, rtt_swm, stat_win, stats_timer, inflight_phase...), добавлены bbr*, delivered_bytes, bbr_pacing_rate
- struct INFLIGHT_PACKET: +3 поля для rate_sample (delivered_at_send, inflight_at_send, is_app_limited)
- etcp_ack_recv: вызов bbr_main() с rate_sample, обновление inflight_lim_bytes и pacing
- etcp_request_pkt: заполнение BBR rate_sample полей при отправке
- Шейпер: bandwidth обновляется из bbr_pacing_rate
- Конфиг: inflight_min/max заменены на bbr_max_cwnd
- Дамп: BBR поля (mode, cycle, pacing, min_rtt_us, bw_hi/lo, inflight_hi/lo)
- Time injection: bbr->now_tb для детерминированных тестов
- tests/test_etcp_bbr.c: 8 юнит-тестов (init, startup, full_bw/drain, loss, cwnd cap, loss cut, fast_path, probe_rtt)
- Отключены test_etcp_congestion и test_etcp_reinit_inflight (старый congestion control)
- 40/40 тестов пройдено
