Assistant panel: Markdown footnotes ([^id] / [^id]: definition) not rendered

[aeterno-caspian]

Body

Markdown footnote syntax ([^identifier] for markers and [^identifier]: content for definitions) is not rendered in the Assistant panel. The raw syntax appears as plain text rather than rendering as linked superscript markers with corresponding footnote definitions.

Steps to reproduce

1. Open the Assistant panel
2. Ask the model to output footnotes in any form:

   This has a footnote[^1].
   
   [^1]: This is the footnote content.
   

3. Observe that the marker renders as literal text [^1] and the definition renders as a plain line

Expected behavior

Footnote markers should render as superscript linked references, and footnote definitions should render as a collected footnote section (bottom of message or expandable inline), consistent with GitHub Flavored Markdown or similar renderers that support the footnote extension.

Context

Footnotes are part of the PHP Markdown Extra / GFM extended syntax and are supported by GitHub's markdown renderer, Obsidian, and other tools. They enable structured elaboration without interrupting prose flow, which is particularly useful in assistant responses that carry technical depth alongside accessible explanations.
