[shabsi4u]

Add comprehensive synthetic data generator with Python app and notebook

• Add Python app with Hugging Face Inference API integration
• Add Jupyter notebook for local model inference
• Implement intelligent custom prompts with few-shot examples
• Add data templates for users, jobs, products, addresses
• Include comprehensive README with usage instructions
• Add .gitignore to exclude cache and virtual environment files
• Support both cloud inference (on the python app) and local model execution (colab / jupyter notebook)
