Resolves the KM-RAG Polyglot Persistence and Background Ingestion Pipeline Migration task. ### Key Changes 1. **Infrastructure Migration**: Integrated Qdrant (for vector embeddings) and Neo4j (for concept graphs), reducing reliance on PostgreSQL pgvector storage. 2. **Concurrent Background Job**: Implemented a robust Hangfire `EbookIngestionJob` utilizing Polly exponential retries for transient 429 rate limits, executing three core ingestion tasks concurrently via `Task.WhenAll`. 3. **Data Layer**: Standardized database schemas and entities; retained `Pgvector.EntityFrameworkCore` for migration compilation compatibility. 4. **Wasm Client & Tests**: Implemented client support for semantic search and refactored related tests in `QueryTests.cs` to mock `IKnowledgeService`. ### Verification Status - **Build**: Successfully compiles with `dotnet build NexusReader.slnx --no-restore` (0 errors). - **Tests**: All 5 unit tests pass cleanly with `dotnet test NexusReader.slnx --no-restore`. **Resolve** #47 --------- Co-authored-by: Marek Jasiński <jasins.marek@gmail.com> Reviewed-on: #46 Reviewed-by: Marek Jaisński <jasins.marek@gmail.com> Co-authored-by: Antigravity <antigravity@google.com> Co-committed-by: Antigravity <antigravity@google.com>
