feat: support | first filter

[zhaob1n]

the chat template in unsloth/Qwen3-Next-80B-A3B-Thinking-GGUF uses | first

{%- set reasoning_content = ((content.split('</think>')|first).rstrip('\n').split('<think>')|last).lstrip('\n') %} {%- set content = (content.split('</think>')|last).lstrip('\n') %}

That's strange, @danielhanchen why would you replace [0] and [-1] from the original template?

@xcpky Anyway, it's an obvious omission from minja, thanks for the submission! :)

Thanks @xcpky !

Oh hi sorry didn't see this - this was probs ages ago to support LM Studio not parsing [0], [-1] correctly, hence the |first and |last
