* nemotron_h: add MLX vision support

Implement the RADIO vision encoder and projector on the shared MLX media pipeline, including dynamic-resolution preprocessing, deterministic placeholder expansion, chunked feature scattering, and MTP offsets.

Expose source-advertised Nemotron vision while continuing to suppress unsupported audio, and preserve both modality towers at source precision during create.

Harden Nemotron streaming parser termination and add focused coverage for vision configuration, media placement, capability reporting, and tool-call parsing.
