feat(gallery): add parakeet-cpp-nemotron-3.5-asr-streaming-0.6b; bump parakeet.cpp pin

Adds the multilingual prompt-conditioned streaming model to the gallery (q8_0
default, OpenMDW-1.1) and bumps the parakeet-cpp backend pin to the parakeet.cpp
commit that ships nemotron support plus batched causal subsampling and the
batched target_lang C-API.
