McpToolRegistrationService: The CancellationTokenSource has been disposed

Description

I'm running the sample https://github.com/microsoft/Agent365-Samples/tree/main/dotnet/agent-framework/sample-agent and could not get the Mcp tools to work.

I got the error below, seems like the method https://github.com/microsoft/Agent365-dotnet/blob/9d2f7e2c4921b51a18c86f48f64e05b31d8c4713/src/Tooling/Extensions/AgentFramework/Services/McpToolRegistrationService.cs#L114-L119 is missing the cancellationToken
