kevmxn/Rolando-bot — reverse-engineered prompt

Build me a simple Python bot called Rolando from this repo and make it feel complete enough to run without me having to figure out the wiring.

I want it to start from main.py, use the included database if that file is meant to store bot data, and be set up so I can run it locally or deploy it easily with Docker and Render. Please keep the setup straightforward, use environment variables for any secrets or tokens, and make sure the app fails gracefully with helpful messages if something is missing.

If the bot is supposed to answer messages, handle basic commands, or read from the database, wire that up in a clean way instead of leaving placeholders. Add a small amount of sensible structure, comments only where they help, and a short usage section so I know how to start it and what config I need. If anything is unclear from the repo, make the simplest reasonable version and look up current docs online if you need to.
