- Change OnReceiveMessage signature to use `object data` (was `SignalData`), enabling type-aware and raw byte[] payloads.
- Implement three-path argument deserialization: byte[] fast-path, IsRawBytesData, and eager typed deserialization via SignalDataType.
- Add SignalDataType and IsRawBytesData fields to SignalParams for protocol guidance.
- Write path now uses AcBinarySerializer zero-copy to pipe; byte[] uses fast-path.
- SequenceBinaryInput now dynamically sizes scratch buffer for large cross-segment reads.
- Deserializer now advances segments before throwing end-of-buffer, improving multi-segment support.
- Set client logging to Debug for better diagnostics.
- Update all docs and markdown to reflect new protocol, dispatch model, and field semantics.
- AyCodeBinaryHubProtocol is now an empty derived class for registration/future hooks; SignalData is no longer the primary payload type.
- SignalResponseDataMessage is now an internal DTO with RawResponseData as object? (typed or byte[]), and GetResponseData<T>() is a direct cast.
