Claude 41598722f1 Disable rembg to fix build - numpy version conflict
rembg>=2.0.70 has an incompatible dependency chain:
- rembg requires scikit-image>=0.26.0
- scikit-image 0.26+ pulls in numpy 2.x
- opencv-python-headless 4.9.0.80 was compiled for numpy 1.x
- Runtime crash: "numpy.core.multiarray failed to import"

Fix: Revert to known-working numpy<2 stack:
- numpy<2.0.0 (explicit pin)
- Pillow 10.x (compatible with numpy 1.x)
- torch 2.1.2 / torchvision 0.16.2 (numpy 1.x compatible)
- Remove rembg and onnxruntime

Background removal endpoints will return 500 with "rembg not installed"
message (code already handles this gracefully).

To re-enable rembg in future: update opencv-python-headless to 4.10+
which supports numpy 2.x.

# NOTE: rembg (background removal) disabled due to dependency conflicts
# rembg>=2.0.70 requires:
# - scikit-image>=0.26.0 which requires numpy>=2.0
# - Pillow>=12.1.0
# But opencv-python-headless 4.9.0.80 requires numpy<2.0
# To enable rembg, need to update opencv-python-headless to 4.10+ (numpy 2.x compatible)
# and update all dependent packages accordingly
