Don't send files referenced from inside liquid template comment tags

[ferrislucas]

See the example below where the file /abc/test.txt is referenced from inside a liquid comment block. The contents of the file are sent to the LLM, but I wouldn't expect them to be because the file reference is not part of the prompt.

Example:

Instructions here

{% comment %}
// this file shouldn't be included in the prompt sent to the LLM
See file /abc/test.txt
{% endcomment %}
