Vaysen Product Image Factory 0.1.0-preview.1

First runnable Windows x64 portable preview.

- Local JPG/PNG/BMP/GIF/TIFF batch processing.
- Aspect-fit resize, JPEG quality, transparency flattening, text watermark,
  safe sequential rename, metadata removal, CSV manifest, progress and cancel.
- Same-directory temporary writes followed by no-overwrite atomic commit.
- 200 MB input file, 100 MP source, 40 MP output and classic 260-character
  Windows path safety boundaries.
- Headless self-test covering valid and corrupt images, Chinese/space paths,
  unchanged input hashes, collisions, repeat runs, CSV formula neutralization,
  manifests and pixel limits.

Preview limitations:
- No AI background removal or advanced annotation.
- GIF animation and multi-page TIFF use the first frame only.
- Input subdirectories are not scanned.
- Re-encoding removes EXIF/GPS/ICC/copyright/C2PA metadata. Keep originals and
  visually inspect colors before publishing.
