FS-LLM，拼写错误导致训练round数无法被正确赋值，怎么设置都只跑了10round

**Bug复现**

standalone模式下，多个GPU训练，线程数大于1， 会生成StandaloneMultiGPURunner
` if mode == 'standalone':
if process_num <= 1:
runner_cls = StandaloneRunner
else:
runner_cls = StandaloneMultiGPURunner`

然后再runner初始化的时候，
total_round_num 被写成了totol_round_num

server初始化这个参数是10。

Start by locating StandaloneMultiGPURunner and inspect its initialization of the total round count, comparing it with the server's default of 10. Reproduce standalone multi-GPU training with more than one thread and verify that the configured round count is honored instead of always running 10 rounds.
