LongCat-Flash-Omni 模型：https://github.com/meituan-longcat/LongCat-Flash-Omni

Start with swift/megatron/argument/train_args.py, where the reported assertion rejects model/LongCat-Flash-Omni. Compare the supported-model handling with the LongCat-Flash-Omni repository linked in the issue, then reproduce the provided SFT command. Done means the model is recognized and this training command proceeds past argument validation.
