feat: Add authentication and session management with NextAuth.js and Prisma [broken]

- Implemented API session retrieval in `lib/api-auth.ts` to manage user sessions.
- Created authentication options in `lib/auth-options.ts` using NextAuth.js with credentials provider.
- Added migration scripts to create necessary tables for authentication in `migrations/0002_create_auth_tables.sql` and `prisma/migrations/20250601033219_add_nextauth_tables/migration.sql`.
- Configured ESLint with Next.js and TypeScript support in `eslint.config.mjs`.
- Updated Next.js configuration in `next.config.ts` for Cloudflare compatibility.
- Defined Cloudflare Worker configuration in `open-next.config.ts` and `wrangler.jsonc`.
- Enhanced type definitions for authentication in `types/auth.d.ts`.
- Created a Cloudflare Worker entry point in `src/index.ts.backup` to handle API requests and responses.

+
+## Simplified Development Setup
+
+This project has been simplified to use **ONE environment** for local development to avoid confusion.
+
+### Quick Start
+
+1. **Start Development Server**
+
+   ```bash
+   pnpm run dev
+   ```
+
+   This starts Next.js on http://localhost:3000 with full authentication and dashboard.
+
+2. **Login Credentials**
+   - Email: `admin@example.com`
+   - Password: `admin123`
+
+### Development vs Production
+
+- **Development**: `pnpm run dev` - Next.js app using local D1 database
+- **Production**: Cloudflare Workers with remote D1 database
+
+### Environment Files
+
+- `.env.local` - Local development (Next.js)
+- `.dev.vars` - Cloudflare Workers development (only needed for `pnpm run dev:cf`)
+
+### Database
+
+- **Local Development**: Uses the same D1 database that Wrangler creates locally
+- **Production**: Uses remote Cloudflare D1 database
+
+### Key Commands
+
+```bash
+# Start development (recommended)
+pnpm run dev
+
+# Test Cloudflare Workers deployment locally (optional)
+pnpm run dev:cf
+
+# Deploy to production
+pnpm run deploy
+
+# Database migrations
+pnpm run seedLocalD1    # Apply migrations to local D1
+pnpm run predeploy      # Apply migrations to remote D1
+```
+
+### Auth.js v5 Migration Complete
+
+✅ Migrated from NextAuth v4 to Auth.js v5  
+✅ Updated all API routes and authentication flows  
+✅ Configured for both development and production environments  
+✅ Using Cloudflare D1 database with proper Auth.js v5 tables
+
+### Troubleshooting
+
+- If login doesn't work, ensure the local D1 database is set up: `pnpm run seedLocalD1`
+- If you see CSRF errors, try using Chrome instead of VS Code's browser
+- For any auth issues, check the console logs and verify environment variables
