Implement complete Docker setup for Next.js 16 frontend with multi-stage builds, hot reload support, and production optimizations. Changes: - Add Dockerfile with multi-stage build (deps, builder, development, production) - Add .dockerignore to exclude unnecessary files from Docker context - Add .env.local.example template for environment configuration - Update next.config.ts with standalone output for production builds - Add Docker convenience scripts to package.json for easy container management - Support hot reload in development with volume mounts - Use Node.js 20 Alpine for smaller image size - Implement security best practices (non-root user in production) Technical Details: - Development stage: Full source mounted with hot reload via Turbopack - Production stage: Standalone build with optimized static assets - Image size: ~1.17GB (development), smaller for production - Port: 3000 (maps to container port 3000) Testing: - Docker build verified for development target - Container startup successful with Next.js 16.0.1 - HTTP 200 response confirmed on localhost:3000 - Hot reload functional with volume mounts 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
