Branch: claude/init-nexus-ummid-012oEX5Es7kVK7uJm29JSjaF
…7kVK7uJm29JSjaF

## Summary

Complete implementation of the **Nexus-UMMID Entertainment Discovery Platform** for the Agentics Hackathon. This PR delivers a production-ready metadata API deployed to Google Cloud Run with semantic search capabilities, multi-platform connectors, and AI-powered enrichment.

### 🚀 Live Deployment
**Service URL:** https://nexus-ummid-api-181630922804.us-central1.run.app

## Key Features

### 1. Metadata API (Full CRUD)
- RESTful API for entertainment metadata management
- Pagination, filtering, and validation
- Auto-generated asset IDs with EIDR support

### 2. Platform Connectors (3 Industry Standards)
| Connector | Standard | Use Case |
|-----------|----------|----------|
| **Netflix IMF** | Interoperable Master Format | Premium content packaging with Dolby Vision HDR |
| **Amazon MEC** | EMA Avails v2.5 | Multi-territory rights management |
| **FAST MRSS** | Media RSS | Pluto TV, Tubi, Samsung TV+, Roku Channel |

### 3. Semantic Search Infrastructure
- **RuVector** in-memory vector search (<100µs latency)
- **Vertex AI** text-embedding-004 integration (768 dimensions)
- Hybrid search with score fusion (RRF algorithm)

### 4. AI-Powered Enrichment
- Automatic mood tag generation
- Platform-specific validation
- Pattern learning with AgentDB

### 5. Production Deployment
- Multi-stage Docker build (Node.js 20 Alpine)
- Cloud Run auto-scaling (0-100 instances)
- Cloud Monitoring alerts and dashboards
- GitHub Actions CI/CD pipeline

## API Endpoints Verified

| Endpoint | Method | Status |
|----------|--------|--------|
| `/health` | GET | ✅ |
| `/api/v1/metadata` | GET/POST | ✅ |
| `/api/v1/metadata/:id` | GET/PUT/DELETE | ✅ |
| `/api/v1/metadata/:id/enrich` | POST | ✅ |
| `/api/v1/metadata/:id/validate` | POST | ✅ |
| `/api/v1/search` | GET | ✅ |
| `/api/v1/search/similar/:id` | GET | ✅ |
| `/api/v1/search/trending` | GET | ✅ |
| `/api/v1/search/stats` | GET | ✅ |

## Tech Stack

- **Runtime:** Node.js 20, TypeScript 5.x
- **Framework:** Express.js with OpenAPI validation
- **Database:** In-memory + Firestore (production)
- **AI/ML:** Vertex AI Embeddings, Matching Engine
- **Orchestration:** Claude-Flow with 13-agent SPARC swarm
- **Deployment:** Cloud Run, Artifact Registry, Cloud Build

## Test Plan

- [x] Health endpoint returns 200
- [x] CRUD operations work on `/api/v1/metadata`
- [x] Platform validation (Netflix, Amazon, FAST) returns valid
- [x] AI enrichment adds moodTags
- [x] Search infrastructure initialized
- [x] TypeScript compiles with no errors
- [x] Docker image builds successfully
