• Stabilized Rational mode with smart rational approximation for irrational numbers (Issue #140).
• Throws an error for ambiguous division of unitless values by quantities with units (Issue #138).
• Small non-zero values now use scientific notation instead of rounding to 0.00 (Issue #141).
• Optimized app startup by removing flickering loading indicator (Issue #139).
• Reduced app size by enabling R8 minification and resource shrinking, and removing unused legacy Material library dependency.
