tokenizer not working

[rui-costa]

The instruction to download weights seem outdated and not aligned with the new available in HeatMula repo

# Create checkpoint directory
mkdir -p ckpt

# Download HeartMuLa (3B model)
huggingface-cli download HeartMuLa/HeartMuLa-oss-3B --local-dir ckpt/HeartMuLa-oss-3B

# Download HeartCodec
huggingface-cli download HeartMuLa/HeartCodec-oss --local-dir ckpt/HeartCodec-oss

# Download tokenizer
huggingface-cli download HeartMuLa/HeartMuLa-oss-3B tokenizer.json --local-dir ckpt

vs

# if you are using huggingface
hf download --local-dir './ckpt' 'HeartMuLa/HeartMuLaGen'

## To use version released on 20260123 (recommended)
hf download --local-dir './ckpt/HeartMuLa-oss-3B' 'HeartMuLa/HeartMuLa-RL-oss-3B-20260123'
hf download --local-dir './ckpt/HeartCodec-oss' HeartMuLa/HeartCodec-oss-20260123

I am currently testing, and will update the documentation once I have validated it works

running the last command for the tokenizer gives the error:

Entry Not Found for url: https://huggingface.co/HeartMuLa/HeartMuLa-oss-3B/resolve/main/tokenizer.json.
