Unexpected keyword argument 'progress_callback'" #175

@bradenmacdonald

fast-agent doesn't seem to work with the recently-released mcp==1.9.0. Because of this change (I think), now running an agent gives this error:

MCPAgentClientSession.send_request() got an unexpected keyword argument 'progress_callback'

I believe this code needs to be updated to accept the new parameter.

For now I downgraded to mcp==1.8.0 and it works around the problem.
