exchange ed25519_pubkey in both handshake directions

- topo_node_sqlite_node_load(): загрузка TOPO_NODE (ref=0) из БД
- cm_start_phase_direct: db_loaded-ветка — перебор всех адресов без NAT-фильтра

- conn_mgr_destroy до etcp_router_destroy (исправлен порядок)
- test_conn_mgr: +2 сценария (DB-успех, DB-недоступен), проверка topo_group
- find_third_node: use nd->inst->connections instead of group->senders_list
- on_conn_up callback auto-calls trigger_checks (no BGP handshake needed)
- Remove group param from link_ready, request_check_all — nat_detection self-sufficient
- Remove trigger_checks + route_ping_cancel_for_conn from public API (internal only)
- topo_group.c: removed last nat_detection_trigger_checks call — completely decoupled
- Header: 4-line summary, no duplicate function list, 7 public functions
- Renamed TOPO_BGP to TOPO_GROUP with topo_group_id (64bit)
- Added TOPO_GROUPS container (ll_queue group_list) in UTUN_INSTANCE
- Memory pools moved from TOPO_GROUP to TOPO_GROUPS (instance-level)
- Default group: TOPO_GROUP_UTUN = 0x8000000000000000
- topo_groups_get_default() searches by group_id, not just first entry
- All topo_bgp_* renamed to topo_group_*; function signatures updated
- Files: topo_bgp.h/c -> topo_group.h/c
- NODEINFO_MSG (protocol, packed): added flags byte + group_id field
- NODEINFO (memory): ref_count, linked list heads instead of inline arrays
- NODEINFO_ROUTES: separate struct with linked list subnet heads
- NODEINFO_Q: node*, routes*, tranzit_data*, hop_list* as separate mallocs
- 6 memory_pools in ROUTE_BGP for NI_* linked list items
- ni_list_count() universal counter via _ni_head cast
- nodeinfo_serialize/deserialize for protocol <-> memory conversion
- NODEINFO_FLAG_SEND_SUBNETS controls subnet data in protocol
- group_id defaults: utun=NODEINFO_GROUP_UTUN(1) with subnets
Fixes:
- deserialization: data+2 instead of data+sizeof(BGP_NODEINFO_PACKET)
- memset: start after ll_entry to preserve ll.size
- hop_src: subtract hop_count*8 to point at correct dynamic offset
- same-ver branch: remove_path(conn) instead of remove_path_by_hop(peer)
- double-free in route_bgp_remove_conn/process_withdraw
- conn_mgr_add_alien_node: rewritten for new structures
- all test files updated for new API
- Add --hardened flag to build.sh with FORTIFY, stack protector, PIE, RELRO
- Add --enable-hardening to configure.ac
- F-001: fix %s -> %.32s to prevent stack leak from non-null-terminated network string
- F-002: add pre-check recv_len >= MAX before buf_space computation to prevent size_t underflow
- TRANSIT_QUEUE: отдельная очередь на каждую пару src+dst узлов
- ll_queue с хеш-индексом для быстрого поиска transit-очередей
- backpressure через waiter на send_input_q (threshold=0, один пакет за вызов, round-robin)
- Очередь создаётся при первом пакете который не получается отправить напрямую, удаляется при опустошении
- Унифицирован etcp_send: единый путь queue_data_put(send_input_q) для UDP (normalizer->input) и STCP (tx_queue)
- Убран STCP-ветвления из router_forward_transit/drain_cb
- Исправлено перекрытие ll.data и tq->q в TRANSIT_QUEUE (добавлены явные поля src_node_id/dst_node_id)
- Фикс лика dgram в tx_queue_cb/client_tx_queue_cb (добавлен queue_dgram_free)
- transit_queues живут внутри ETCP_CONN, инициализируются лениво, очищаются в etcp_connection_close (до pn_deinit) и stcp_link_close
- route_node_format_all(): format all BGP nodes to snprintf buffer
- control_server: 'nodes' action sends ETCPMON_RSP_ACTION_RESULT (0x89) with text
- etcpmon_protocol.h: new response type + struct, increase MAX_MSG_SIZE to 32K
- etcpmon_client: on_action_result callback, send_action via send_request with seq_id
- etcpmon_gui: ETCPMonActionResult popup window class with EDIT multiline,
on_action_result creates popup (same size as main) or appends text + scrolls
Add route_node_dump_all() in route_node.c that walks bgp->nodes list
and outputs per-node info: node_id, name, version, pubkeys, IPv4/IPv6
addrs/sockets/subnets, paths with hop list, connectivity state, conn_mgr.
Wire 'nodes' action in control_server to call this function.
- Add rx_dup_count (local) and tx_dup_count (remote via ACK) to ETCP_CONN
- Extend ACK section format: add 16-bit rx_dup_count after last_delivered_id
- Reconstruct 32-bit tx_dup_count from received 16-bit diff
- Update etcpmon protocol and control_server to expose counters
- Update packet dumper for new ACK format
- 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
