caldrix v0.1.2

Added

• The smollm2-instruct alias (HuggingFaceTB/SmolLM2-135M-Instruct), a SmolLM2 with a chat template
  for caldrix run. Its tokens are verified on the CPU lane (x86-64-v3) on a plain-text prompt; it is
  not verified on Metal or AMD GPUs, and no check covers the chat template.

Changed

• caldrix run with a model that has no chat template (such as smollm2) stops each reply at 256
  tokens unless --max-tokens is given; before, a base model could run until the context filled.
