Update DB config, docs, and SignalR binary protocol setup
- Switched appsettings.json connection string to production DB.
- Added "Shared Agent Skills" section to copilot-instructions.md in both main and Mango.Nop Libraries repos.
- Refactored PluginNopStartup.cs: improved using statements, updated SignalR to use AddAcBinaryProtocol with explicit options, removed manual IHubProtocol registration, and added protocol diagnostics.
- No business logic changes; focused on configuration, documentation, and infrastructure.
Changed connection string to use FruitBank_DEV database. Updated DI registration of AyCodeBinaryHubProtocol to use custom AcBinarySerializerOptions with BufferWriterChunkSize set to 4096. Added import for AyCode.Core.Serializers.Binaries and included a commented alternative DI approach.
Updated the connection string in appsettings.json to use the FruitBank_PROD database instead of FruitBank_DEV. Changed the SignalR hub protocol registration in PluginNopStartup.cs from AcBinaryHubProtocol to AyCodeBinaryHubProtocol.
Registered custom AcBinaryHubProtocol as a singleton IHubProtocol
in PluginNopStartup.cs to enable efficient binary messaging
(via AcBinarySerializer) and eliminate JSON/Base64 overhead.
Updated SIGNALR_ENDPOINTS.md to document the new protocol,
noting WebSocket (TransferFormat.Binary) requirement and
affected hubs (DevAdminSignalRHub, LoggerSignalRHub).
Explicitly set StatefulReconnectBufferSize to 30 MB in both
code and documentation.
Refactored Mango.Sandbox.EndPoints to enable minimal, dependency-light SignalR endpoint testing. Introduced DevAdminSignalRHubSandbox and TestSignalREndpoint for protocol/contract tests without full NopCommerce/FruitBank infra. Added SignalRClientSandbox and comprehensive MSTest coverage for all parameter types. Simplified Program.cs startup, updated project references, and added minimal logger. Original SignalREndpointTests replaced with focused, low-level and high-level tests. CORS and DTOs updated for compatibility.
