The issue was that links in the markdown view (used for user messages, tool outputs, etc.) were styled with text-primary, which resolves to the same color as the background or main text in some themes (effectively making them invisible or indistinguishable). I updated the WYSIWYGEditor configuration to use standard blue coloring for links in both light and dark modes. (#1418)

**Changes applied:**

1.  **Modified `frontend/src/components/ui/wysiwyg.tsx`**:
    -   Updated the `theme.link` property to use `text-blue-600` (light mode) and `dark:text-blue-400` (dark mode).
    -   Added hover states `hover:text-blue-800` and `dark:hover:text-blue-300` for better interactivity.

This change ensures links are clearly visible and themed correctly in user messages and all other places where the `WYSIWYGEditor` is used for markdown rendering.

I verified the changes by running `pnpm run check`, which passed successfully.
