[Bug]: `qwen3-vl.py` filename uses hyphen instead of underscore

[xiaomin-D]

Description

File slime/backends/megatron_utils/megatron_to_hf/qwen3-vl.py uses a hyphen in its name, but __init__.py imports it as qwen3_vl:

from .qwen3_vl import convert_qwen3vl_to_hf

Python module names cannot contain hyphens, causing:

ModuleNotFoundError: No module named 'slime.backends.megatron_utils.megatron_to_hf.qwen3_vl'

Fix

Rename the file:

mv qwen3-vl.py qwen3_vl.py
