This PR successfully adds LaTeX/math rendering support to the MarkdownRenderer component. The implementation correctly integrates KaTeX with the React Markdown pipeline using remark-math and rehype-katex plugins.
Changes:
- Added required dependencies (
katex,remark-math,rehype-katex) - Configured ReactMarkdown with math processing plugins
- Added appropriate CSS styling for rendered math expressions
The implementation is sound and ready to merge after addressing the minor file formatting issue.

Add a newline at the end of the file. Missing final newlines can cause issues with version control systems and certain build tools that expect POSIX-compliant text files.

Code Review
This pull request integrates mathematical expression rendering into the MarkdownRenderer component using remark-math, rehype-katex, and katex. Feedback includes correcting a non-existent version number for the katex dependency, removing a vertical overflow restriction in the CSS to prevent clipping of tall expressions, and configuring the KaTeX plugin to handle syntax errors gracefully without crashing the component.

The version 0.16.44 for katex does not appear to exist on npm. The current latest version in the 0.16.x branch is 0.16.11. This typo will likely cause installation or build failures.

Setting overflow-y: hidden on .katex-display can cause clipping of tall mathematical expressions, such as large matrices, fractions, or summations with limits. It is recommended to only use overflow-x: auto to handle horizontal scrolling for long equations without risking vertical clipping.

By default, rehype-katex will throw an error if it encounters invalid LaTeX syntax, which can crash the entire rendering of the component. It is safer to set throwOnError: false so that KaTeX renders the problematic string as-is (usually in red) instead of throwing an exception.
