- Added AcBinaryHubProtocolOptions for unified protocol configuration (serializer, mode, buffer size, flush strategy, timeout, name, logger) with validation and DI support.
- Refactored AcBinaryHubProtocol and AyCodeBinaryHubProtocol to use options object; legacy constructors now delegate to options-based API.
- Added per-chunk flush timeout to AsyncPipeWriterOutput and AcBinarySerializer; throws TimeoutException on slow consumers.
- Improved XML docs and comments for pipeline/backpressure/timeout clarity.
- Updated SIGNALR_BINARY_PROTOCOL.md to document new options and AsyncSegment platform rules.
