Add initial implementation of Deal Intel project

This commit introduces the foundational structure for the Deal Intel project, including:
- Environment configuration file (.env.example) for managing secrets and API keys.
- Scripts for building a ChromaDB vector store (build_vector_store.py) and training machine learning models (train_rf.py, train_ensemble.py).
- Health check functionality (health_check.py) to ensure system readiness.
- A launcher script (launcher.py) for executing various commands, including UI launch and health checks.
- Logging utilities (logging_utils.py) for consistent logging across the application.
- A README file providing an overview and setup instructions for the project.

These additions establish a comprehensive framework for an agentic deal-hunting AI system, integrating various components for data processing, model training, and user interaction.
