Antigravity 081c6f7940 fix(infra): use bash socket healthcheck for qdrant in staging and test (#68)
This Pull Request fixes the Qdrant startup error on the Staging and Testing environments.

### 🔍 Cause of the Bug
The official `qdrant/qdrant:latest` image is built on `debian-slim` and **does not contain `curl` or `wget`**. Changing the healthcheck to `curl` caused Qdrant to exit with status `127` (command not found), marking the service as unhealthy/error in Docker.

### 🛠️ Solution
Reverts the healthcheck in both `docker-compose.stage.yml` and `docker-compose.test.yml` to the robust, built-in bash TCP socket check:
```yaml
    healthcheck:
      test: ["CMD-SHELL", "bash -c 'exec 3<>/dev/tcp/127.0.0.1/6333'"]
```

Successfully validated locally and tested compilation.

📖 Nexus Reader

Nexus Reader is a state-of-the-art, cross-platform Blazor .NET 10 immersive e-book reader, powered by Native AOT, Clean Architecture, CQRS, and interactive D3.js Relationship Graphs built on vector-based AI semantics.


Features & Architecture Highlights

📁 Ingestion & Description persistence

  • Extracted and persistent book descriptions from EPUB package metadata during book ingestion.
  • The Description field propagates cleanly from the Ebook entity through Mapster to LastReadBookDto and UserProfileDto.
  • Implemented deep-link route activation: /reader/{bookId}?chapter=N.
  • Allows instant resume of reading session coordinates and loads the specific chapter chapter directly via URL query parameters.

🛡️ Downstream AI Resilience

  • Standard resilience engine in DependencyInjection.cs utilizing the Polly package (ai-retry).
  • Automatically intercepts, handles, and retries on both rate-limits (429 Too Many Requests) and downstream capacity overloads (503 ServiceUnavailable / high demand).

⚙️ Concurrent Request Deduplication

  • Multi-client InteractiveAuto Blazor circuit synchronization is backed by a thread-safe active task registry in KnowledgeService which ensures that identical concurrent requests await a single shared task instance, eliminating redundant LLM queries.

🛠️ Build & Verification Gate

Ensure the dotnet workload matches the active SDK, and compile the full solution utilizing:

dotnet build NexusReader.slnx --no-restore

Run test suite:

dotnet test --no-restore
