feat(llama-cpp): generic chat_template_kwargs merge (drop per-key blocks)

Replace the per-key enable_thinking/reasoning_effort handling in both the
streaming and non-streaming chat paths with a single block that parses the
chat_template_kwargs JSON blob resolved by the Go layer and merges every key
into body_json. New jinja template levers (e.g. preserve_thinking) now need
no C++ change. Issue #10329.
