sungeer/actress ? reverse-engineered prompt

Build me a small Python web app called Actress that runs locally with uvicorn on port 8848.

I want it to feel like a simple agent service that uses a database connection pool and a thread pool so it can handle requests smoothly and do work in the background without blocking. It should start up cleanly, have a basic home page or status endpoint, and let me see that the app is alive and ready. If there’s a sensible place for a simple demo action or job runner, include that too so it’s obvious the threading and DB setup are being used.

Please make it easy to install with a virtual environment and pip, and keep the code organized and readable. If you need to check current docs for any libraries or the best way to wire things together, go ahead and look them up.
