agentscope-ai/agentscope-java ? reverse-engineered prompt

Build me a Java 17 agent framework demo app that shows how to run a helpful assistant with long running tasks, tool use, and safe human approval when needed. I want it to support live event updates so I can see what the agent is doing in real time, plus a simple chat style interface or example flow that makes it easy to test. Include a way to connect to a model provider by config, and let the agent use tools in an isolated workspace so it can do things like read and write files without touching my real machine.

Please also show a small multi agent example where one agent can spawn or send work to another agent, and make the session survive restarts with persistence. If there are good defaults for local mode, Docker, or a simple production setup, include those too. Keep it clean, practical, and ready to run, and look up current docs online if you need to.
