Complete System Validation Script for Video Processor v0.4.0

This script validates that all four phases of the video processor are working correctly:
- Phase 1: AI-Powered Content Analysis
- Phase 2: Next-Generation Codecs & HDR
- Phase 3: Adaptive Streaming
- Phase 4: Complete 360° Video Processing

Run this to verify the complete system is operational.
