- Added explicit=true to pytorch-cu121 index
- Only torch, torchvision, torchaudio use PyTorch index
- All other packages (requests, fastapi, etc.) use PyPI
- Fixes: requests version conflict (PyTorch index has 2.28.1, we need >=2.31.0)
How explicit=true works:
- PyTorch index only checked for packages listed in tool.uv.sources
- Prevents dependency confusion and version conflicts
- Best practice for supplemental package indexes
- Changed from 'default' to named additional index
- Added tool.uv.sources to specify torch comes from pytorch-cu121 index
- Other packages (fastapi, uvicorn, etc.) still come from PyPI
- Fixes: 'fastapi was not found in the package registry' error
How it works:
- PyPI remains the default index for most packages
- torch package explicitly uses pytorch-cu121 index
- Best of both worlds: CUDA PyTorch + all other packages from PyPI
Changes:
- Set PyTorch CUDA index (cu121) as default for all builds
- CUDA builds support both GPU and CPU (auto-fallback)
- Fixes uv run reinstalling CPU-only PyTorch
- Updated dependency-groups syntax (fixes deprecation warning)
Benefits:
- Simpler build process - no CPU vs CUDA distinction needed
- uv sync and uv run now get CUDA-enabled PyTorch automatically
- Builds work on systems with or without NVIDIA GPUs
- Fixes issue where uv run check_cuda.py was getting CPU version

- Web server is always-running (not optional) for OBS integration
- Users no longer need to manually install fastapi and uvicorn
- Previously required: uv pip install "fastapi[standard]" uvicorn
- Now auto-installed with: uv sync
Fixes: Missing FastAPI/uvicorn dependencies on fresh Windows installs
