bootstrap

Scaffold a new web project from an empty directory to a fully-working, agent-ready codebase: Vite + React + TypeScript + shadcn/ui + Supabase + Netlify + Playwright, with GitHub repo, deploy previews, CI workflows, and Claude-friendly conventions (CLAUDE.md, REVIEW.md, StepReport, docs/). Hands off to the `/sprint` skill for feature work. Use when the user asks to "bootstrap a new project", "start a new app", "scaffold from scratch", or invokes `/bootstrap` directly. Do NOT use on an existing project — run it only in an empty or near-empty directory.
