- Add PostgreSQL database with SQLAlchemy async support - Create models: User, UserFact, UserPreference, Conversation, Message, Guild, GuildMember - Add custom name support so bot knows 'who is who' - Add user facts system for remembering things about users - Add persistent conversation history that survives restarts - Add memory commands cog (!setname, !remember, !whatdoyouknow, !forgetme) - Add admin commands (!setusername, !teachbot) - Set up Alembic for database migrations - Update docker-compose with PostgreSQL service - Gracefully falls back to in-memory storage when DB not configured
