Quickstart: a barebones Convex template, running

Stand up a barebones Next.js + Convex template from the idea, locally, with an anonymous dev deployment. Minimal by design: local dev servers, no publish step, no pre-baked auth.

Workflow

1. Run recipe quickstart-recipe@^2 with {idea, template} (the pack fetches + caches it; pinned offline fallback). It creates the project, installs deps, starts the backend (anonymous) and the web dev server.
2. When it prints the dev URL, open it for the user.
3. Present a short plan and CONFIRM before building features beyond the template.
