bcd37ba55f Implement comprehensive 360° video processing system (Phase 4)
This milestone completes the video processor with full 360° video support:

## New Features
- Complete 360° video analysis and processing pipeline
- Multi-projection support (equirectangular, cubemap, EAC, stereographic, fisheye)
- Viewport extraction and animated viewport tracking
- Spatial audio processing (ambisonic, binaural, object-based)
- 360° adaptive streaming with tiled encoding
- AI-enhanced 360° content analysis integration
- Comprehensive test infrastructure with synthetic video generation

## Core Components
- Video360Processor: Complete 360° analysis and processing
- ProjectionConverter: Batch conversion between projections
- SpatialAudioProcessor: Advanced spatial audio handling
- Video360StreamProcessor: Viewport-adaptive streaming
- Comprehensive data models and validation

## Test Infrastructure
- 360° video downloader with curated test sources
- Synthetic 360° video generator for CI/CD
- Integration tests covering full processing pipeline
- Performance benchmarks for parallel processing

## Documentation & Examples
- Complete 360° processing examples and workflows
- Comprehensive development summary documentation
- Integration guides for all four processing phases

This completes the roadmap: AI analysis, advanced codecs, streaming, and 360° video processing.

cfda5d6777 Implement comprehensive 360° video processing support
Core Features:
- 360° video detection via metadata, aspect ratio, and filename patterns
- Automatic projection type identification (equirectangular, cubemap, etc.)
- 360° thumbnail generation with multiple viewing angles (front, back, up, down, stereographic)
- 360° sprite sheet creation for immersive video players
- Enhanced metadata extraction with spherical video information

Configuration:
- Optional 360° settings in ProcessorConfig with validation
- Bitrate multipliers for 360° content (typically 2.5x for quality)
- Configurable thumbnail projections and generation options
- Graceful degradation when optional dependencies unavailable

Architecture:
- Modular design with optional dependency detection
- Video360Detection class for intelligent 360° identification
- Thumbnail360Generator for perspective and stereographic projections
- Video360Utils for bitrate/resolution recommendations
- Extended VideoProcessingResult with 360° outputs

Testing & Examples:
- Comprehensive test suite covering detection, configuration, and integration
- Working example demonstrating 360° processing workflow
- Proper error handling and dependency validation

Backward Compatibility:
- All existing functionality preserved
- 360° features completely optional and isolated
- Clear error messages when dependencies missing
