Replace the trigger-policy change with the version-matrix bump requested by
Comfy: test on Python 3.14/3.13/3.12/3.11 against PyTorch 2.12 on CUDA 13.2.
- pass cuda_version through to comfy-action (was defaulting to 12.1)
- pin torch 2.12 + torchvision from the cu132 wheel index via the action's
'specific' install path (requires the Linux 'specific' branch in comfy-action)
- torchaudio omitted: no cu132 build for these Python versions
- Commented out Windows OS from the CI matrix in test-ci.yml.
- Removed the test-win-nightly job to streamline testing on macOS and Linux only.
- Adjusted the matrix strategy to focus on Python versions and CUDA compatibility without Windows support.
