Register MultiScaleDeformableAttention in mmcv ATTENTION registry

Add sigmoid_focal_loss, deform_conv2d, get_onnxruntime_op_path to shim

Add missing mmcv.ops stubs: RoIPool, DeformConv2d, etc.

Fix apt package: libgl1-mesa-glx -> libgl1 for Debian Trixie

Fix PyTorch install URL: use --extra-index-url for CPU wheels

Fix Dockerfile: extract mmcv.ops shim to separate Python file

Fix: inline MMCV_WITH_OPS=0 in RUN + --no-build-isolation

Use mmcv-full with MMCV_WITH_OPS=0 (skip C++ extension build)

Switch to Docker SDK for reliable mmcv-full build

Fix requirements: use --extra-index-url for torch, remove gradio dup

Fix build: pin torch 1.13 + mmcv-full pre-built wheel

Initial deploy: AutoLineDigitizer Gradio API for HuggingFace Spaces
