feat: Smart Queue Consumer implementation draft + architecture review

- SMART_QUEUE_IMPLEMENTATION.md: Complete implementation draft (1572 lines)
  with 10 quick-win fixes and full smart queue consumer rewrite
- ARCHITECTURE_REVIEW.md: 26-issue audit with prioritized findings
- Verified all 3 GPUs live: amdpve (73% util), llmgpu (idle), ocu_llm (idle)
- Redis 7.4.9 confirmed streams support
- GPU sidecar metrics verified on all hosts

Key fixes:
- QW-1: Dockerfile path mismatch (Dockerfile.queue -> queue-service/Dockerfile)
- QW-2: Nginx fallback only on ALL-GPU failure (not single GPU)
- QW-3: Container names fixed to Docker service names
- QW-4: Redis host default fixed (192.168.68.7 -> redis)
- QW-5: Dependency version pinning
- QW-7-10: Health checks, restart policy, Gunicorn, single-process collector

Smart queue features:
- Redis Streams + consumer groups
- GPU-aware load balancing via sidecar metrics
- Per-GPU circuit breakers with half-open recovery
- Adaptive backpressure (0-30 normal, 30-40 warn, 40-50 503, >50 open)
- Dead letter queue with retry endpoint
- Job ID tracking and /status/<job_id> API

+
+## Components
+
+| Service | Port | Container | Purpose |
+|---|---|---|---|
+| Nginx Router | 8080 | Host | Routes requests to GPU backends |
+| Queue Service | 8091 | `syslog-queue` | Enqueues requests when GPUs are down |
+| Dashboard | 3001 | `syslog-dashboard` | Observability UI + API |
+
+## GPU Routing
+
+| Header `X-Syslog-Model` | Backend | Model |
+|---|---|---|
+| (none) / `standard` | amdpve (.15) | qwen3.6-35B-A3B (MoE) |
+| `heavy` / `qwen3.5-27B` | llmgpu (.8) | qwen3.5-27B (Dense) |
+| `light` / `gemma-4` | ocu_llm (.110) | gemma-4-E4B (Light) |
+
+## Quick Start
+
+```bash
+# Build & start
+docker compose build
+docker compose up -d
+
+# Verify
+curl http://localhost:8091/health
+curl http://localhost:3001/api/status
+```
+
+## Dashboard
+
+- **UI:** `http://<host>:8080/dashboard/harness.html`
+- **API:** `http://<host>:8080/dashboard/api/status`
+
+## Circuit Breaker
+
+- Rate limit: 10 req/s per IP
+- Burst: 20 requests
+- Excess returns 503
+- Queue fallback on GPU 502/503
