Resolves #75 ### Description This pull request implements a smart, Native AOT-compliant contextual recommendation engine for the desktop dashboard to drive user retention and cross-book monetization. ### Key Changes 1. **Application Layer**: - Declared `IUserReadingStateStore` interface to decouple reading state discovery. - Added `IVectorSearchStore.SearchGlobalExcludeAsync(...)` to abstract semantic similarity searches with exclusions. - Defined `GetContextualRecommendationsQuery` and response DTOs (`ContextualRecommendationResponse`, `RecommendationDto`). 2. **Infrastructure Layer**: - Implemented `UserReadingStateStore` using EF Core with DbContext pooling. - Implemented `SearchGlobalExcludeAsync` in `VectorSearchStore` to construct gRPC Qdrant filters (excluding the active book ID) and fetch `bookTitle` and `chapterTitle` from point payloads. - Implemented `GetContextualRecommendationsQueryHandler` using clean abstractions. 3. **Web & Serialization Layer**: - Mapped `GET /api/recommendations` endpoint. - Registered types in `AppJsonContext.cs` for AOT-compliant JSON serialization. 4. **Verification**: - Added complete unit test coverage in `GetContextualRecommendationsQueryTests.cs`. All 30 unit tests pass. --------- Co-authored-by: Marek Jasiński <jasins.marek@gmail.com> Reviewed-on: #76 Co-authored-by: Antigravity <antigravity@google.com> Co-committed-by: Antigravity <antigravity@google.com>
