Goal

This PR migrates the core logic, models, and services from the private repository to the public one. It introduces a comprehensive set of features including intent detection, a RAG engine, WooCommerce integration, and a leads pipeline, while optimizing the overall architecture and logging.

Changes

• Core & Config: Updated application configuration, database setup, and added necessary dependencies (Poetry lockfile updated).
• Models & Schemas: Introduced new data models and schemas for handling leads, chats, and WooCommerce orders.
• Services: Implemented core business logic including intent detection, RAG engine processing, and WooCommerce smart parsing.
• API Endpoints: Updated v1 REST API endpoints to support the new chat and lead ingestion pipelines.
• Middleware: Added rate limiting and request logging middleware for better security and observability.
• Frontend & Deployment: Updated frontend chat widgets, scripts, and Docker/Prometheus configurations.
• Testing: Updated the test suite to cover the newly introduced features and integrations.

How to Test

1. Run poetry install to update all dependencies.
2. Ensure Docker containers (e.g., PostgreSQL, Redis, Prometheus) are running via docker-compose up -d.
3. Start the application server using poetry run uvicorn app.main:app --reload.
4. Run the test suite with poetry run pytest to verify that all components are functioning correctly.
5. Interact with the /api/v1/chat and /api/v1/leads endpoints via Swagger UI (/docs) to test the intent detection and leads logic.
