systxd/quartz ? reverse-engineered prompt

Build me a TypeScript monorepo for a Discord bot framework that feels easy to extend and safe to use.

I want a modular client adapter setup where different Discord bot clients can plug in, events are strongly typed, and plugins can add features without a lot of boilerplate. It should be set up as a clean workspace with a shared core package and room for docs or examples, so it’s easy to grow later.

Please make the starter actually usable, not just empty scaffolding. Include a simple example of creating a bot, listening for typed events, and registering a plugin. Keep the code tidy and modern, and if you need to check current best practices or package docs online, go ahead.
