remix-run/remix ? reverse-engineered prompt

Build me a full stack web framework in TypeScript that feels modern and portable across Node, Bun, Deno, and Workers. I want the whole thing centered on web standards and the Fetch API, with small reusable pieces for routing, requests and responses, cookies, sessions, form handling, file uploads, auth, logging, headers, and basic database helpers. It should also include a simple CLI, a way to run app code with TypeScript and JSX, and a component system that can render on the server and hydrate in the browser.

Please organize it as a monorepo with clear standalone packages, but make it easy to use as one main framework package too. Add a few demos and a basic starter template so I can see how the pieces fit together. If anything needs current runtime or platform details, look up the latest docs online first.
