Implement story integration foundation: - Create Domain/Entities/StorySegment.cs with full CRUD methods - Create Domain/Entities/StoryProgress.cs for user story progress tracking - Create Application/DTOs/StorySegmentDto.cs with multiple DTO types - Create Domain/Interfaces/IStoryRepository.cs - Create Domain/Interfaces/IStoryProgressRepository.cs - Create Infrastructure/Data/Repositories/StoryRepository.cs - Create Infrastructure/Data/Repositories/StoryProgressRepository.cs - Add DbSets and entity configurations to AppDbContext - Add navigation properties to Level, Lesson, and User entities Next: Phase 2 - Backend Services (StoryService, StoryGenerationService) Generated by Mistral Vibe.
