Add Hosted-Invocations-EchoAgent: a minimal echo agent hosted via the Invocations protocol (POST /invocations) using AddInvocationsServer and MapInvocationsServer, bridged to an Agent Framework AIAgent through a custom InvocationHandler. Add SimpleInvocationsAgent: a console REPL client that wraps HttpClient calls to the /invocations endpoint in a custom InvocationsAIAgent, demonstrating programmatic consumption of the Invocations protocol. Both samples default to port 8088 for consistency with other hosted agent samples.
