refixshow/coaching-platform — reverse-engineered prompt

Build me a solid first version of a coaching platform as a monorepo. I want a web app people can open in the browser, with basic routing and a clean starting structure for the main coaching flows, plus a Convex backed data layer so the app actually has a working backend instead of just static screens.

Please also keep a shared Discord integration layer in place so this project is ready for Discord features later, even if the full bot app is only scaffolded for now. The main thing is that the web app, backend sync, environment setup, and core commands all work smoothly in local development.

Keep the code organized and easy to extend, since this looks like it will grow into more apps and shared packages. Add sensible starter docs and make sure the root env files are used correctly across the repo. If anything is unclear, look up current docs online and make practical choices that fit this setup.
