- Add NodeConfig: simplified INI config manager for embedded uTun node
- X25519 key generation via OpenSSL EVP
- Random node_id generation
- addServer/removeServer, addClient/removeClient API
- Auto-creates config with default server on first run
- Integrate UtunNode into MainWindow:
- Creates NodeConfig in ~/.config/chatgui/node.conf
- Starts embedded uTun node (no TUN, no msg_transport)
- In separate thread with uasync_poll event loop
- Replace MsgClient (TCP IPC) with UtunNode (direct calls):
- ChatPropagator now uses UtunNode for send/recv
- send(uint64_t, QByteArray) replaces sendTo
- messageReceived signal replaces received signal
- MainWindow cleanup: remove MsgClient, add UtunNode+NodeConfig
- UtunNode runs uTun instance in a dedicated std::thread
- no TUN, no msg_transport — direct etcp_route_send/recv calls
- Thread-safe cross-thread communication via Qt signals
- C callback (etcp_recv_fn) stores UtunNode* via thread_local
- etcp_router_bind on service ID 0x11 for chat messages
- uasync_poll(100ms) loop runs until stop() called
- Add tools/chatgui/libutun/CMakeLists.txt — builds libuasync (from lib/*.c)
and libutun (from src/*.c except utun.c) as static libraries
- All C code compiled as C99, linked into chatgui C++ binary
- Include paths and defs match autotools build
- chatgui CMakeLists.txt: add_subdirectory(libutun), link utun library
- Fix zxing-cpp docs/ directory issue
