Major Changes: - Set up SQLx database connection and migration system - Create complete initial database schema with all tables - Rename 'auction' to 'listing' throughout codebase for better terminology - Update bot commands: /newauction -> /newlisting, /myauctions -> /mylistings - Update all database tables: auctions -> listings, auction_medias -> listing_medias - Update foreign key relationships and indexes - Add automatic database migration on startup - Update documentation and README - Complete backlog tasks: task-001, task-002, task-010 The bot now has a solid database foundation ready for implementing core business logic. All tests pass and code compiles successfully.
