Pull request overview
This PR migrates all GitHub Actions workflows and composite actions from using pip to uv for package management, which should improve CI performance through faster dependency resolution and installation. The changes replace actions/setup-python with astral-sh/setup-uv@v7, update all package management commands to use uv pip, and introduce new caching optimizations with uv cache prune --ci.
Key changes:
- Replaced Python setup with uv setup across all workflows and added built-in caching via
enable-cache: true - Converted all pip commands to their uv equivalents (uv pip install, uv pip list, uv build, etc.)
- Added
UV_TORCH_BACKEND: cpuenvironment variable to workflows installing PyTorch for optimized CPU-only installations - Updated the cache composite action to remove pip caching logic since uv handles its own caching
