Dockerfile Generator

# Dockerfile Generator

## Description
Generate an optimized multi-stage Dockerfile for the given project.

## Steps
1. Detect the project type (language, framework, package manager)
2. Choose appropriate base images (slim/alpine when possible)
3. Implement multi-stage build to minimize final image size
4. Set up proper layer caching (dependencies before source code)
5. Configure non-root user for security
6. Add health check if applicable

## Best Practices
- Pin base image versions
- Use .dockerignore
- Minimize layers
- Don't copy unnecessary files
- Set WORKDIR
- Use COPY over ADD
