fix: FORTIFY vsnprintf crash on Android + foreground service type
...
Root cause: etcp_on_up/etcp_on_down/etcp_conn_process_send_queue
used fixed buffers (links_str[256], l_status[256]) with snprintf
chains in loops over links. With 15+ links (IPv6 addresses),
sizeof(buf)-offset turned negative → vsnprintf size=(size_t)(-17)
→ FORTIFY abort on Bionic.
Fixes:
- lib/strbuf.h/c: safe growable printf buffer (auto-realloc)
- etcp.c: 3 snprintf chains → strbuf
- debug_config.c: BUF_ADVANCE macro prevents offset overflow
- android_jni_bridge.c: bridge_log va_list fix, set_member_flags guard
- chat_core.c: TAGS_ADVANCE macro in tags_commit
- AndroidManifest.xml: dataSync→specialUse (time limit exhausted)
- stcp: ed25519 pubkey exchange, tcp link addr/status in JNI bridge
- etcp_router: encrypted flag + ECDH per peer-pair
- node_conn_direct: TCP link support
- topo_node: group nodes cleanup
- media_delivery: buffer overflow fix
- test_stcp: ed25519 key exchange test
- tests: invite_group_create + Makefile update

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)

feat: integrate Opus codec into lib/libopus + voice messages in chatgui
...
- Add lib/libopus/ (opus v1.6.1 embedded source: CELT 18 .c, SILK 77 .c, SILK float 28 .c, OPUS core 14 .c)
- Add lib/opus_codec.h/.c (wrapper: encoder, decoder, raw PCM int16)
- Add tests/test_opus_codec.c (7 tests: silence, sine, compression, PLC, null, defaults, multi-frame)
- chatgui: AudioRecorder (miniaudio capture, 48kHz mono)
- chatgui: VoiceEncoder (PCM→Opus file with custom container)
- chatgui: VoicePlayer (Opus→PCM playback via SoundManager)
- chatgui: PTT button in InputBar, voice message send/receive in MessageList
- chatgui: AudioDeviceSettingsPage (device selection, persisted in ui_state)
- chatgui: MessageDelegate voice message rendering (play button + duration)
- Update autotools: configure.ac, Makefile.am, src/Makefile.am, tests/Makefile.am
- Update CMake: chatgui CMakeLists.txt, libutun CMakeLists.txt (link libopus_internal.a)
