Add V2V, V2I, 2D-to-3D conversion, and cluster documentation

Features Added:
- Video-to-Video (V2V): Style transfer, filters, concatenation
- Video-to-Image (V2I): Frame extraction, keyframes, collages
- 2D-to-3D Conversion: SBS, anaglyph, VR 360 formats
- Video upscaling with AI (ESRGAN, Real-ESRGAN, SwinIR)
- Video filters (grayscale, sepia, blur, speed, slow-mo, etc.)

Command-line Arguments:
- --video: Input video file for V2V/V2I operations
- --video-to-video: Enable V2V style transfer
- --video-filter: Apply video filters
- --extract-frame, --extract-keyframes, --extract-frames
- --convert-3d-sbs, --convert-3d-anaglyph, --convert-vr
- --upscale-video, --upscale-method

Model Discovery:
- Added depth estimation models to --update-models
- Added 2D-to-3D model searches
- Added V2V style transfer models

Documentation:
- Updated README.md with new features
- Added comprehensive V2V/V2I/2D-to-3D examples
- Added multi-node cluster setup guide
- Added NFS shared storage configuration
