Attach packet drivers to initially empty ETCP connections. Share BLE neighbor
tracking and group fallback between desktop and Android in cgathui_common.
Deliver join links through a dedicated Write/Indicate characteristic with
independent fragmentation queues, application acknowledgements, deduplication
and bounded retries. Merge LAN/BLE discovery and add a separate Bluetooth
invitation reception setting to both clients.
Validation: 230 core tests, BLE transport/BlueZ/UI tests, ASAN/UBSAN,
Linux GUI and Android builds, and Windows backend cross-compilation.
Physical Android/Linux invitation exchange passed with either GATT initiator.
The Android-initiated run also verified all 32 ETCP packets of 1500 bytes;
the desktop-initiated load run reached 7/32 within its 45-second time limit.
- 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
- Замена контекстного меню 'Пригласить' на кнопку + (18x18) справа снизу каждого канала с hover-эффектом
- InviteDialog: авто-копирование ссылки в буфер (Clipboard + Selection) при открытии
- JoinDialog: параметр autoJoinLink — если в буфере валидная utun:// ссылка, диалог сразу стартует подключение
- chat_core_connect_from_invite: add TOPO_SOCKMETA4 (id=0, UNKNOWN, UNKNOWN)
so cm_has_direct_ip/cm_start_phase_direct can match socket_id=0 addr
- conn_mgr: cm_bg_ping_timer_cb reads real addr from nq->node->v4_addrs
instead of NULL; added cm_bg_ping_noop_cb per required etcp_send_ping_to_socket
- invitedialog: set both QClipboard::Clipboard and Selection on Linux/X11
