Changes:
- Modified IncrementalVideoStitcher to process IMAGE tensors directly instead of MP4 lists.
- Implemented RAM/VRAM saving mechanism by saving tensor state dynamically to `.pt` files and cleaning them manually via `gc`.
- Introduced LoadVideoWithSourceAudio mapping to extract complete original tracks dynamically.
- Created `video.py` introducing the `FFmpegVideoStitcher` node to concatenate video chunks generated via sequential batch loops.
- Registered the node into ComfyUI's standard mapping dictionaries in `__init__.py`.
- Added check for FFmpeg installation using `shutil.which` and raising a ComfyUI-friendly error if it's missing.
- Updated node output file saving logic to utilize ComfyUI's native `folder_paths.get_output_directory()`.
- Revised `README.md` and `README_ES.md` with explicit instructions on how to set up the workflow (VHS Combine integration) and provided warnings emphasizing the need for `easy cleanGpuUsed` after VAE decoders to prevent PyTorch OOM exceptions during iterative batching loops.
