{#- Tool-capable Llama-3 chat template for the Fairleap corpus.

    The stock Sahabat-AI template renders every message as
    `content | trim` and ignores both `tool_calls` and the `tools` argument.
    On this corpus that is silent data loss, not an error: an assistant
    tool-call turn carries `content: ""`, so it renders as an *empty*
    assistant reply and the call disappears. ~10% of the corpus is shaped
    that way.

    Two things this adds:
      1. assistant `tool_calls` render as the one-line JSON the model is
         meant to emit, and `role: tool` results come back as a `user` turn
         wrapping `<tool_response>` so response-only masking still works
         (see the note on that branch);
      2. the `tools` schema list is folded into the system turn, so
         "tool offered" and "tool not offered" are distinguishable in
         context. Without that the model cannot learn when *not* to call.
