gopisai123/DeliverX ? reverse-engineered prompt

Build me the Phase 1 foundation for DeliverX, a last mile delivery management and tracking app.

I want a clean React web app and a simple Express API that work together, with TypeScript throughout. The web app should be set up with a nice starting UI using Tailwind, and the API should have a working health check at /health. Please make sure the project is wired for local development so I can run the web app and API separately, and keep the code organized for future growth.

Set up the shared package for common validation, types, enums, and constants, and connect the Prisma and PostgreSQL foundation so the project is ready for future database work. Keep this first phase focused on the base structure only, not auth, dashboards, orders, pricing, assignment, tracking, or notifications yet.

Use the existing environment setup and make sure the repo passes typecheck, lint, and build. If you need to check current docs online for anything, feel free to do that.
