Remove Docker dependencies and configuration from this project.

Your task:
1. Identify all Docker-related files and configurations:
   - Dockerfile
   - docker-compose.yml
   - .dockerignore
   - Docker-specific scripts
   - Docker references in documentation

2. Create a plan for migration:
   - Extract environment variables to .env or config files
   - Document local development setup requirements
   - Identify system dependencies previously in Docker image
   - Update README with non-Docker setup instructions

3. Remove Docker files and update documentation:
   - Delete Docker configuration files
   - Update README and documentation
   - Create setup scripts for local development if needed
   - List system dependencies and installation instructions

4. Ensure smooth transition:
   - Verify no application logic depends on Docker-specific features
   - Update CI/CD pipelines if needed
   - Provide clear migration guide
