Merge WebSocket client functionality into HttpClient using Boost.Beast,
enabling a single client instance to handle both HTTP (libcurl) and
WebSocket (ws:// and wss://) protocols. Backward-compatible type aliases
(WebSocketClient, WebSocketClientBase) preserve existing code.
Changes:
- Add synchronous WebSocket client: ws_connect/ws_send/ws_recv/ws_close
- Support ws:// (plain TCP) and wss:// (TLS with SNI) connections
- Layered stream architecture with beast::tcp_stream for timeout support
- Binary message support via ws_send_binary()
- Update Makefile to link libcurl (-lcurl)
- Add README.md documenting unified HttpServer + HttpClient API
Merge WebSocketServer functionality into HttpServer so a single port can
serve both HTTP(S) and WebSocket(S) endpoints while preserving full backward
compatibility for existing HTTP interfaces.
Key changes:
- Add WebSocket route registration: ws(), onWsConnect(), onWsDisconnect()
- Add client management: sendToWsClient(), broadcastWs(), disconnectWsClient()
- Rewrite Session class using beast::tcp_stream for unified HTTP/WS handling
- Support automatic ws:// and wss:// upgrades on HTTP/HTTPS ports
- Thread-safe message queue with asio::post for cross-thread sends
- Update Makefile to link OpenSSL and pthread for TLS/WebSocket support
- Add test_server.cpp demonstrating HTTP + WebSocket mixed usage
