feat: Implement Walmart scraper and integrate with existing architecture
- Added Walmart scraper to scrape product data from Walmart.com, including category pages and product details. - Introduced a stealth browser module to handle bot protection and improve scraping reliability. - Created a SQLite database for tracking product history, price changes, stock events, and user favorites. - Developed a Discord bot for user interaction, allowing location setting and stock checking at local stores. - Implemented a favorites system to manage priority products and categories with custom notification settings. - Added news aggregation module to fetch and analyze Pokemon TCG news from various sources. - Created tools for API discovery and monitoring, including a backend monitor for detecting new products. - Added unit tests for database operations, product filtering, and API endpoints to ensure functionality. - Enhanced existing modules with improved error handling and logging for better maintainability.
