Problem Statement

Issue:
LaTeX math rendering using $$...$$ syntax is inconsistent in the Claude Code VSCode extension chat window. Sometimes formulas render correctly, sometimes they appear as plain text.

Proposed Solution

Expected behavior:
Stable math formula rendering (e.g. via KaTeX or MathJax) in the conversation window.

Example:
$$\hat{\beta} = (X^TX)^{-1}X^Ty$$
Should render as a formatted formula, not plain text.
