topo: invite вынесен в topo_group_invite, conn_mgr упрощён до 3-фазного open; member_sync: полный пересчёт merkle-дерева при старте
...
- topo_group_invite.c/h: invite/join через DIRECT + INVITE_INFO_REQ/RESP (из conn_mgr)
- conn_mgr: conn_mgr_open_invite → conn_mgr_open, убран invite-режим (-480 строк)
- topo_group_connect: подключение через node_conn_direct вместо conn_mgr
- member_sync: _rebuild_all_trees сносит merkle_tree_hash канала и собирает заново из peers (чистка осиротевших листов)
- member_sync: хеш блока A/B (update_sig/adm_tags) в док-комментариях

keepalive handshake: device_type + keepalive negotiation in UDP/TCP INIT
...
- Добавлен device_type (1 байт, CLIENT_TYPE_*) в INIT_REQUEST и INIT_RESPONSE
- Добавлен keepalive_interval (2 байта) в INIT_RESPONSE
- STCP handshake расширен с 43 до 46 байт (device_type+keepalive)
- negotiate_keepalive(): оба desktop/server → min, иначе (есть mobile) → max
- keepalive_interval вынесен в UTUN_INSTANCE для использования в handshake
- stcp_client_connect() принимает device_type и keepalive_interval
- peer_device_type/peer_keepalive_interval передаются через stcp_link в ETCP_LINK

fix chatgui: prevent invite deadlock on connection flap

cs_on_conn_down: remove invite state zeroing on disconnection.
Only timeout callbacks and explicit protocol end (CS_MSG_ERROR,
transition to JOIN phase) clear the invite state.
Connection flap now causes automatic retry:
conn_up → pending_invite_ch_id != 0 && !info_req_timer → resend
CHANNEL_INFO_REQ. No deadlock possible.

fix: use-after-free in route table — add route_delete before u_free in route_bgp_update_my_nodeinfo and route_bgp_process_nodeinfo, relax routes_overlap to allow hierarchical routes
...
Root cause: when bgp->local_node was reallocated (changed=1), old route
entries remained with stale v_node_info pointing to freed memory. The freed
memory got reused by a BGP peer's NODEINFO_Q, causing route_lookup to return
wrong node_id (b3b2b1b0afaeadac instead of local), which then failed at
etcp_route_send with 'no BGP route' and dropped packets to 10.23.2.1.
Changes:
- route_node.c: route_delete(old) before u_free + route_insert(new) after alloc
- utun_instance.c: remove duplicate route_insert (now atomic inside function)
- route_bgp.c: route_delete before freeing old peer NODEINFO_Q
- route_lib.c: routes_overlap now rejects only exact prefix+network duplicates
- tests/Makefile.am: add route_lib.o to test_route6_lib
