MonobyteStudios/OnlyOneMessage — reverse-engineered prompt

Build me a Discord bot for server admins called OnlyOneMessage. I want it to give really fine control over text channels through slash commands, especially custom slowmode rules that can last way longer than normal Discord limits, even for hours, days, or forever. It should work per channel, let members talk again if they delete their previous message, and keep useful logs for when someone enters cooldown and when that cooldown ends.

Please make it self hostable with Docker, using a Mongo database, with simple config files and env values so I can drop in my bot token and run it. It should support a production and development mode, plus optional extras like metrics, error tracking, and API or top.gg integration only if enabled in config. Add sensible admin only dev commands, background tasks, and event handling for message flow.

Make it feel polished and practical for real Discord moderation. Include a clear setup flow and example config so I can run it quickly. If anything is unclear, check current Discord bot docs online.
