Add comprehensive system validation script

This script validates all four phases of the video processor:
- Configuration system with validation
- AI-powered content analysis
- Advanced codecs integration
- Adaptive streaming capabilities
- Complete 360° video processing
- Core processor integration

Results: 5/6 components operational (codecs require system FFmpeg)

+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.
