This PR finalizes the implementation of issue #35 by establishing a formal foreign key relationship between `KnowledgeUnit` and `Ebook`. Closes #35 ### Changes: - **Domain**: Refactored `KnowledgeUnit` to use `Guid EbookId` and added navigation property. - **Data**: Updated `AppDbContext` fluent configuration and generated a new migration. - **Service**: Updated `IKnowledgeService` and its implementations to propagate `ebookId`. - **API**: Updated Web API endpoints to support linking extracted knowledge to specific ebooks. ### Verification: - [x] Solution builds successfully (`dotnet build`). - [x] Schema changes verified in migration file. - [x] Cascading delete behavior confirmed. --------- Co-authored-by: Marek Jasiński <jasins.marek@gmail.com> Reviewed-on: #43 Co-authored-by: Antigravity <antigravity@google.com> Co-committed-by: Antigravity <antigravity@google.com>
