Major protocol update: OnReceiveMessage now takes metadata (SignalReceiveParams) and payload (byte[]) as separate hub arguments, not a single envelope. Metadata is AcBinary-serialized; payload uses protocol fast-path. Updated all client/server code, interfaces, and docs. Added ISignalParams and SignalReceiveParams types. Improved AcBinaryHubProtocol diagnostics and made byte[] fast-path more robust. This enables clearer, more debuggable, and future-proof SignalR binary messaging.
Removed OnReceiveStreamMessage from both AcSignalRClientBase and IAcSignalRHubBase, eliminating client-to-server streaming support. Updated StreamAsync calls to use the explicit method name string. This change enforces server-to-client streaming only and cleans up related interface and method references.
