dexlens/monorepo ? reverse-engineered prompt

Build me a clean TypeScript monorepo for Dexlens that I can use as a starting point for the project.

I want the repo organized in a sensible way with separate areas for apps, shared code, scripts, templates, and any data or third party pieces that need to live in the repo. Make it easy to add more apps or packages later without everything becoming messy. Set up the basics so the project feels ready to work in right away, with clear structure, simple defaults, and good developer experience.

If there are any choices you need to make for tooling or setup, use modern sensible defaults and keep it lightweight. I’d also like a README that explains the purpose of the repo at a high level and how someone on the team should get started. If you need to check current docs online for anything, go ahead and do that.
