ChatML reference template — used by Qwen 2.5, SmolLM2, and compatible |

models. Source-of-truth for Go `text/template` round-trip tests: |
| 4 |
rendering these messages through this Jinja and the Go template must |
| 5 |
produce token-identical sequences after tokenization. |
| 6 |
|
| 7 |
Render `{"messages": [...]}` where each message has `role` in |
| 8 |
{"system", "user", "assistant"} and a `content` string. Call with |
| 9 |
`add_generation_prompt=True` to append the trailing assistant cue. |
