MINT-bridgev2

MINT checkpoint from outputs/btm_bridge_v2/checkpoints/100000/pretrained_model. The matching action tokenizer is MINT-tokenizer-bridgev2.

The vqvae_name_or_path config field points to huangrm/MINT-tokenizer-bridgev2/vqvae.pth. The MINT loader in this LeRobot checkout resolves that path using hf_hub_download.
