Bump CI matrix to Python 3.14-3.11, PyTorch 2.12, CUDA 13.2

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
