AccessibilityVisitor class
Accessibility Visitor: Converts the LaTeX AST into screen-reader-friendly text descriptions.
Follows MathSpeak-style reading rules to provide natural language descriptions of mathematical formulas for visually impaired users.
Usage example:
final description = AccessibilityVisitor.describe(document);
// "fraction: 1 over 2" for \frac{1}{2}
