Add Vercel deployment scripts and documentation

Added npm scripts:
- npm run deploy - Deploy preview to Vercel
- npm run deploy:prod - Deploy to production

Added deployment section to README with:
- Simple deployment commands
- Instructions for setting up environment variables
- Link to Vercel dashboard

Makes deployment a single command for users.
