v0.19.0

Oriel 0.19.0

Added

• oriel.llama.ChatTemplates: a model's own Jinja chat template serves an
  OpenAI chat request the way llama-server does (llama.cpp's
  common/chat.cpp): messages with tool calls and results, tools,
  response_format and the thinking switch render in the model's native
  format; the answer samples with the template's lazy tool-call grammar and
  parses back into content, reasoning and tool calls, streamed as it grows.

Changed

• .llama builds llama.cpp's common library (its CLI and download parts
  aside) instead of the JSON-schema converter alone.
