Original GitHub issue: https://github.com/ollama/ollama/issues/14008

In the code block below, JSON encoder is created for every token.

It may increase GC pressure during streaming, especially for long responses, and it seems we can reuse the encoder so that optimize it.

It should be fix in both ollamarunner and llamarunner
