agentjido/jido — reverse-engineered prompt

Build me a small Elixir example app that demonstrates Jido in a way I can run locally and understand quickly.

I want it to show the basic idea of autonomous agents without needing any AI model keys. Make a simple workflow with a few agents that keep their own state, react to incoming signals, run actions, and return clear results. Something like a task coordinator with worker agents is fine, as long as it shows state changes, events flowing through the system, supervision, and a graceful failure or retry example.

Please set it up like a normal Mix project, include the Jido instance module, config, supervision wiring, a couple of actions, and tests that prove the workflow works. Add a short README with commands to install deps, run tests, and try the demo in IEx.

Keep the code idiomatic Elixir and OTP friendly. Use the current Jido docs online if you need to check the exact APIs.
