Evgeny 1f4fe37fe5 proxy: rename + simplify + backpressure 
- tcp_proxy/remote_proxy → tcp_proxy_client/tcp_proxy_server
- Все proxy файлы перенесены в src/proxy/
- Конфиг: [tcp_proxy]→[tcp_proxy_client], [remote_proxy]→[tcp_proxy_server]
- Убран subcmd CONNECTED (0x02) — клиент шлёт DATA сразу после CONNECT
- Backpressure: etcp_router_waiter_register/cancel через ll_queue threshold waiter
- Клиент: recv_cb send fail → tx_buf+waiter, не tcp_recved() (окно lwIP=0)
- Сервер: read_cb send fail → pause_buf+waiter, пауза read_id
- CLOSE/ERROR отправляется только после drain всех очередей
- Fail: conn не найден/closed → send ERROR вместо CLOSE/silent drop
- PROTOCOL.md: полная архитектура с диаграммами состояний и потоков

Evgeny 4f0baa37db bbr: исправить передачу потерь в BBR + пол для cwnd на уровне BBR_CWND_MIN_TARGET*mss 
- etcp.c: rs->lost из link->bbr_loss_since_ack (был хардкод 0), вызов bbr_note_loss при ретрансмите
- etcp_connections.h: поле bbr_loss_since_ack для per-link учёта потерь в байтах
- etcp_bbr.c: везде где BBR_CWND_MIN_TARGET — умножить на mss (юнит-мизматч пакеты/байты)
  - bbr_quantization_budget, bbr_set_cwnd, bbr_bound_cwnd_for_inflight_model, bbr_probe_rtt_cwnd
  - bbr_init_lower_bounds: инициализация inflight_hi из cwnd (был ~0U навсегда)
- control_server.c + etcpmon: экспорт BBR-метрик (bw_hi/lo, inflight_hi/lo, режим, потери)
- tests/bbr_integration: интеграционный тест BBR (15с, 50ms/5%loss/1Mbit) с таблицей метрик
- устранён death spiral BBR при высоких потерях: cwnd теперь не падает ниже 4*mss

Evgeny 6c79939db3 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

Evgeny cee9a04348 GUI: add active timeouts and busy memory blocks counters 
- Add timeout_heap_get_size() to get active timer count
- Add global counters in memory_pool: g_total_free and g_total_allocated
- Simplify busy memory calculation to single formula:
  busy = memory_pool_get_total_allocated() - memory_pool_get_total_free_blocks()
- Add new IDC_EDIT_ACTIVE_TIMEOUTS and IDC_EDIT_BUSY_MEMORY to GUI
