Add Milestones 1 & 2: full-stack POS foundation with admin UI
- Node/Express/TypeScript API under /api/v1 with JWT auth (login, refresh, logout, /me) - Prisma schema: vendors, users, roles, products, categories, taxes, transactions - SQLite for local dev; Postgres via docker-compose for production - Full CRUD routes for vendors, users, categories, taxes, products with Zod validation and RBAC - Paginated list endpoints scoped per vendor; refresh token rotation - React/TypeScript admin SPA (Vite): login, protected routing, sidebar layout - Pages: Dashboard, Catalog (tabbed Products/Categories/Taxes), Users, Vendor Settings - Shared UI: Table, Modal, FormField, Btn, PageHeader components - Multi-stage Dockerfile; docker-compose with Postgres healthcheck - Seed script with demo vendor and owner account - INSTRUCTIONS.md, ROADMAP.md, .claude/launch.json for dev server config Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
