c5b737d9bb Line breaking for fractions and radicals fixes 
Implement smart width-checking for complex mathematical displays to enable
  inline rendering when space permits, dramatically improving multiline layout.

  Changes:
  - Add shouldBreakBeforeDisplay() helper to check width before line breaks
  - Add performLineBreak() helper for clean line transitions
  - Modify fraction handling to stay inline when they fit within maxWidth
  - Modify radical handling to stay inline when they fit within maxWidth
  - Support radicals with degrees (cube roots, nth roots, etc.)

d2df078dc9 Add support for dfrac and tfrac LaTeX commands 
Add display-style (dfrac) and text-style (tfrac) fraction commands
  to SwiftMath's LaTeX parser. These commands force fractions to render
  in specific styles regardless of context.

  Implementation:
  - Add dfrac parsing to prepend displaystyle to numerator/denominator
  - Add tfrac parsing to prepend textstyle to numerator/denominator
  - Implement in both parser functions in MTMathListBuilder.swift

  Testing:
  - Add testDisplayStyleFraction() for dfrac validation
  - Add testTextStyleFraction() for tfrac validation
  - Add testDisplayAndTextStyleFractions() for complex expressions
  - All 180 tests pass on macOS and iOS simulator

  Documentation:
  - Update MISSING_FEATURES.md (7/12 features now implemented, 58%)
  - Update README.md feature list to include dfrac and tfrac

  Fixes issue where equations like y'=-\dfrac{2}{x^{3}} would fail to
  parse with "Invalid command dfrac" error. This was blocking the
  StepByStep feature preview rendering.
