Comfy feature, translate

- [x] Task 2
- [ ] Task 3 

to

◻ Task 1
☑ Task 2
◻ Task 3

Currently removed.

Thanks!

Found out an interesting project on pub.dev.
https://pub.dev/packages/gpt_markdown

Dedicated to the agent thread, I think it can be translated to Component.
Would authorize to bind more advanced rendering like tool call.

Pre-Analyze:

• removing latex would make it a pure Dart
• translate 2 or 3 LeafRenderer to Nocterm Single Child
• replace Icon with Text

What you think?

I think Nocterm is different enough from Flutter so that I think it warrants a custom implementation. We do already use the markdown package for parsing!

How do you feel about □ (U+25A1) and ✓ (U+2713) btw?

□ Task 1
✓ Task 2
□ Task 3

More readable but not sure about the convention ✓ can be used elsewhere.
I resolve this case for my component by making them configurable.
This would let your user repect their theme even going with ◎ ◉
