Runs pytest against Python 3.9-3.12 matrix on: - Pull requests to main - Pushes to main Excludes slow tests (pretrained model downloads) for fast CI.
- Added tests/test_train_fabric.py - Added tests/test_cli_train.py - Updated tests/test_train.py to use CPU explicitly - Added VideoRateDistortionLoss to tinify/losses for correct video training support in CLI
