* feat(parakeet-cpp): honor request language (multilingual nemotron) on batched + streaming paths
Reads opts.GetLanguage() and threads it through to the new
parakeet_capi_transcribe_pcm_batch_json_lang and parakeet_capi_stream_begin_lang
C-API entry points, both probed with Dlsym so the backend still loads against an
older libparakeet.so (falling back to the non-lang paths, i.e. model default).
parakeet.cpp's batched C-API takes a single target_lang for the whole batch, so
the dispatcher only coalesces same-language requests: a request whose language
differs from the batch leader is held as a single carry-over and becomes the
leader of the next batch, never dropped and never left waiting (including on
shutdown). A new batcher test asserts no dispatched batch is ever mixed-language
and that every submitted request still receives a reply.

* 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.
