Fam Zheng 7939990181 patch: CN mirrors for pytorch-wheels and HF datasets ...

- pyproject.toml + uv.lock: pytorch-cu128/cpu indexes → mirror.sjtu.edu.cn
  (aliyun lacks 2.9.1, sjtu has it)
- nanochat/dataset.py: climbmix BASE_URL → hf-mirror.com

For ailab (CN, RTX 5090) where direct pytorch.org and huggingface.co
are unreachable. Override at uv-sync time with UV_DEFAULT_INDEX env.

dataloader.py

big, breaking change but large upside: swap previous FineWeb-EDU dataset to NVIDIA ClimbMix dataset. Requires people to download the data shards. The upside is that training GPT-2 capablity model now only takes ~2 hours, down from 2.76 hours, so this is a huge win data-wise
