.NET: [Bug]: CopySessionConfig() hardcodes Streaming = true, ignoring SessionConfig.Streaming value #4732

var sessionConfig = new SessionConfig
{
    Streaming = false, // caller explicitly disables streaming
    SystemMessage = "You are a helpful assistant.",
    OnPermissionRequest = PermissionHandler.ApproveAll,
};
 
var agent = copilotClient.AsAIAgent(sessionConfig);
// Agent always uses streaming regardless — CopySessionConfig ignores source.Streaming

internal static SessionConfig CopySessionConfig(SessionConfig source)
{
    return new SessionConfig
    {
        Model = source.Model,
        ReasoningEffort = source.ReasoningEffort,
        // ... all other properties copied from source ...
        InfiniteSessions = source.InfiniteSessions,
        Streaming = true  // ← hardcoded, should be: source.Streaming
    };
}
