Release v1.0.0

Changes

Added

• Five runnable examples (examples/): market_data_ws_callbacks and market_data_user_thread_callbacks for one or more symbols; multi_websockets_ws_callbacks and multi_websockets_user_thread_callbacks demonstrating two symbols (BTC-USD + ETH-USD, one symbol per WebSocket) sharing a stream_buffer_multiplexer via producer_offset; multi_websockets_ws_callbacks_reader demonstrating cross-process IPC by attaching to the named shared-memory mux and producer buffers written by multi_websockets_ws_callbacks — raw JSON is logged on a second process with no extra network connection
• BUILD_COINBASE_ADVANCED_EXAMPLES CMake option to build examples
• Second WebSocketClient constructor accepting an external slick::stream_buffer_multiplexer, enabling multiple clients to share one multiplexer
• producer_offset parameter on both WebSocketClient constructors to assign non-overlapping producer ID ranges per client
• Buffer-sizing parameters on WebSocketClient constructors: md_read_buffer_size, md_record_size, user_read_buffer_size, user_record_size, write_buffer_size (all with sensible defaults)
• Shared-memory name parameters (md_read_buffer_shm_name, user_read_buffer_shm_name) for zero-copy IPC via named shared memory
• WebSocketClient::marketDataUrl(), userDataUrl(), and streamBufferMultiplexer() accessors
• ProducerType enum (MD_DATA, USER_DATA, MD_CTRL, USER_CTRL) for typed producer-buffer routing

Changed

• BREAKING: Upgraded slick-net from v2.1.0 to v3.0.0; slick-stream-buffer-multiplexer and slick-dynamic-buffer are bundled in slick-net v3.0.0
• BREAKING: UserThreadWebsocketCallbacks constructor no longer accepts a queue_size parameter; buffer sizing is now controlled via WebSocketClient constructor arguments
• BREAKING: WebSocketClient::logData() no longer accepts a data_queue_size parameter
• BREAKING: WebSocketChannel::__COUNT__ renamed to _CHANNEL_COUNT_
• UserThreadWebsocketCallbacks now uses slick::stream_buffer_multiplexer instead of SlickQueue<char> for inter-thread data delivery — zero-copy, lock-free, and multiplexed across multiple clients
• WebSocketClient WebSocket objects are now created at construction time (not lazily on first subscribe())
• dispatchData() now routes to dedicated per-ProducerType producer buffers; raw market/user data is written directly by slick-net's websocket layer, eliminating an extra copy
• Data logger reads from the shared multiplexer using producer IDs rather than a separate queue
• WebSocketClient is now explicitly non-copyable and non-movable
• reset_callbacks() replaced with detach() in destructor (slick-net v3.0.0 API change)
• MessageType::MARKET_DATA and MessageType::USER_DATA removed; data routing is now handled by producer type rather than a message type header
