exchange ed25519_pubkey in both handshake directions

Для новых сокетов добавляются линки ко всем активным NCD-соединениям
При удалении интерфейса линки убираются, сокет закрывается

Android chatgui:
- New MemberListScreen with member list, detail card, edit dialog
- Link status dots (green/red/grey) per address in detail card (1s poll)
- Self-node name coloured green
- ChatScreen: people icon in TopAppBar
IPv6 autoconnect fixes (3 bugs in conn_mgr/topo):
- topo_node_sqlite_node_load: load v6 addresses from DB
- topo_node_registry_store: merge v6_addrs into existing node
- cm_sock_v6_classify: wildcard [::] treated as CM_V6_DIR
- cm_add_v6_link: htons(port) was missing
Memory fixes:
- strdup→u_strdup in bridge (7 instances)

Chat member hash now includes addresses for change detection
Linux chatgui:
- Link status dots in AccountList detail panel (1s poll)
- Self-node name in green in member list
- Создан src/chat/ с chat_event.h/c — система нотификаций
- Перенесены chat_core, chat_msg, chat_channel, chat_profile, chat_status
- Перенесены chat_sync, member_sync, merkle_sync, db_sync
- gui_bridge_post() заменён на chat_event_post() с возможностью регистрации обработчика
- chat_event_set_handler() — chatgui регистрирует мост в gui_bridge
- Без обработчика: события логируются через DEBUG_DEBUG + log_dump
- chat интегрирован в utun_instance.c (при db_path в конфиге)
- Обновлены include-пути, Makefile.am, CMakeLists.txt
- Из chatgui удалены старые transport/ файлы, обновлён utun_node.cpp
- Add last_msg_at column to channels table
- Update last_msg_at on every message insert (send/receive)
- Parameterize getChannels() with ChannelSortMode enum (Alphabetical/Recent)
- Add getChannelLastMessage() for preview text in channel list
- Add sorting combo to Profile settings page (stored in ui_state)
- Reload channels on message receive when sort is recent
- _get_level_hashes: use separate SQL without prefix64<=? for level 0.
UINT64_MAX cast to sqlite3_int64 becomes -1, making prefix64<=-1 always
false for positive prefixes → bitmap always 0 → sync never exchanges data.
- member_sync_init: add _rebuild_all_trees to scan all peers_* tables and
call merkle_sync_recompute_path for each member. Ensures merkle_tree_hash
has entries for members added before merkle sync existed.
- Add 2-byte dlen prefix to terminal BATCH/HASHES data so receiver knows
exact byte count — fixes rem=0 bug that truncated multi-item BATCHes.
- Fix synthetic HASHES prefix_bytes: use merkle_sync_prefix_bytes(next_lvl)
for both declaration and _prefix_write, not current level's pb_i.
- Fix initiator never getting _session_done: responder sends confirmation
HASHES(is_data=1,level=0) before _session_done so initiator's done_cb fires.
- Add level==0 guard in _member_get_items/_member_update_bucket_hash
to prevent SQL queries with bogus mask on virtual root level.
- _get_level_hashes: remove (0x1F << parent_shift) from range_end so
bitmap only includes children of the actual parent prefix (not all
parents). Add level 0 virtual root that queries all level-1 entries.
- merkle_sync_start: send HASHES at level 0 (virtual root) instead of
level 1/prefix 0. Root-level REQUEST prefix reconstruction now uses
the correct level-1 prefix from DB.
- _handle_batch: use merkle_sync_prefix_bytes(next_lvl) for synthetic
child HASHES instead of current level's pb_i (could be wrong size).
- Remove timeout/retry mechanism: delete _session_timeout_cb,
_session_start_timer, timer/retries fields. ETCP provides reliable
transport — no need for application-layer retries.
_prefix_write was writing the least significant pb bytes of the 64-bit
prefix, but the protocol expects the most significant pb bytes (bits
63..64-pb*8). For pb<=4 these ranges are disjoint → wire always got
zeros. _prefix_read also lacked the final left-shift to align the
result at bit 63.
This caused all level>=2 merkle sync requests/batches to receive
prefix=0 instead of the real prefix, making get_items/update_bucket_hash
find zero members → handle_batch len=7 with no data → sync completed
without actually exchanging member data.
