stcp: ed25519 pubkey exchange in handshake, fix instance destroy segfault, fix chat_tcp_test
...
- u_async.c: process immediate_queue BEFORE epoll_wait in uasync_poll
- stcp_link.c: defensive NULL etcp_conn/etcp_link in stcp_link_close
- utun_instance.c: move stcp_server_list_destroy_all to Phase J (before ETCP),
add deferred drain in both Phase J and L
- stcp.h/c: STCP_HS_ENC_CLIENT 6→38, STCP_HS_ENC_SERVER 7→39,
exchange ed25519_pubkey in both handshake directions
- etcp_connections.c: copy peer_ed25519 from STCP to ETCP_CONN in
etcp_link_enter_ready_tcp; guard link->etcp in tcp_link_close_cb
- chat_sync.c: fix lk->conn NULL dereference for TCP links
- test_stcp.c: update stcp_server_create/stcp_client_connect callsites
- tools/chat_tcp_test: change transport udp→tcp

refactor: STCP connections as ETCP links (is_tcp)
...
- Add is_tcp, tcp_link, tcp_reconnect_* fields to ETCP_LINK
- Remove transport_link from ETCP_CONN, add tcp_link_count
- stcp_link: replace embedded etcp_conn with pointer; add etcp_link backpointer
- stcp_link: link_rx_cb routes ETCP data to etcp_conn_input
- stcp_link: call on_close_cb in close
- New TCP functions: etcp_link_enter_ready_tcp, etcp_tcp_link_start_connect,
etcp_tcp_link_start_reconnect, tcp_link_close_cb, etcp_tcp_send
- etcp_link_new: handle NULL conn for TCP links; skip enter_init for TCP
- etcp_link_close: close stcp_link for TCP
- etcp_encrypt_send: redirect TCP to etcp_tcp_send (skips AES-CCM)
- tcp_server_on_link: create ETCP_LINK(is_tcp=1) + enter_ready_tcp
- etcp_connect: TCP addrs -> etcp_tcp_link_start_connect
- Remove ctx->tcp_link/tcp_ready
- test_stcp_traffic: find stcp_link via links->is_tcp instead of transport_link
- 66/68 tests pass; 2 STCP tests expected to fail (integration not complete)

debug: реорганизация категорий — SYS(1), ETCP(4) расширен, CONNECTION(3) очищен; fix stcp_client.c sock_err до connect()
...
Категории:
- DEBUG_CATEGORY_SYS=1: u_async + ll_queue + memory + timing (было 4)
- DEBUG_CATEGORY_ETCP=4: ETCP + normalizer + BBR (было 3)
- DEBUG_CATEGORY_CONNECTION=3: только события статуса линка/подключения (INFO)
- DEBUG_CATEGORY_KEEPALIVE=21: только периодический мониторинг (DEBUG)
- Удалены: NORMALIZER, BBR, CONNECTIVITY
- Устаревшие DB_SYNC → CHAT_SYNC + MEMBER_SYNC (предыдущий коммит)
CONNECTION+INFO — только: Connection UP/DOWN, Link UP/down, Link initialized/added,
NAT address init/changed, init server/client.
CONNECTION+DEBUG — retry, collision, reinit, socket register.
KEEPALIVE — init_timer SUPPRESSED, timer started, keepalive skipped.
REINIT — ETCP+INFO.
Connection status changed — GENERAL (пользовательский callback).
Dedup link_status: if(old_link_status) перед Link down.
Убран дублирующий Conn:%s из Link down, добавлен link_id в client added link.
Молчаливые ошибки: +DEBUG_ERROR в 15 местах (merkle_sync, member_sync, db_sync).
Fix: stcp_client.c — socket_get_error() вызывался ДО connect(), проверяя
застарелое errno вместо ошибки connect(). Неблокирующий connect() возвращает
-1+EINPROGRESS (норма), но сравнивался с мусором → ложный FAIL.
Все 4 STCP-теста исправлены (68/68 pass).

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
