The wrapper is easy: a CLI that sends your brief to a model, writes the files, and starts the dev server is one sitting of work. The model doing the writing is the actual product, and you cannot rebuild that. Everything Lovable puts around it, the hosted preview, the deploy, the database wired up for you, and a non-developer being able to use any of it, goes with the subscription.

Build me a local brief-to-app generator to replace Lovable. Requirements:

- A Node 22 CLI: `vibe new "a habit tracker with a weekly grid"` scaffolds a Vite +
  React + TypeScript app into ./apps/<slug>, then edits it in a loop. Generated apps
  persist to plain JSON or SQLite via better-sqlite3.
- Call the Anthropic or OpenAI API with the key from .env and ask for whole files
  back as JSON, path plus contents, never prose I have to dig out of a code fence.
- Every round is a git commit on a branch and prints the diff first. `vibe undo` is
  a git revert, so nothing the model does is unrecoverable.
- After each round run `npm run build` and `tsc --noEmit`, feed failures back, retry
  three times, then stop and show me the error instead of looping.
- `vibe preview` runs the Vite dev server on localhost:5173. No accounts, no
  telemetry, nothing leaves my machine except the model calls.
- Keep the transcript, file tree, and last diff in .vibe/session.json inside the app,
  resend only the files I named, and print tokens and cost per round.
- Out of scope: hosted previews, one-click deploy, and team collaboration. Do not
  build a web UI, the terminal is the interface.
- README: which key to set, what a typical app costs, and the honest warning that the
  output is only as good as the model behind it.
