Antigravity 23acaeb705 feat: KM-RAG Polyglot Ingestion Pipeline Migration (#46) 
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
