Problem description & steps to reproduce

Extracting official chat templates from chat_template field in tokenizer_config.json (Gemma 2, Llama 3.2, Qwen 2.5), storing them in files, and then trying to use them with llama-server results in errors.

1. Gemma 2: parse: error parsing grammar: expecting name at after each message.
2. Llama 3.2: server doesn't start.
3. Qwen 2.5: parse: error parsing grammar: expecting name at after each message.

@ochafik Could you look into this? It would be nice to have jinja implementation fully working with official templates, at least for major models.
