Comprehensive documentation audit and improvements
Enhanced documentation across all source files for clarity, consistency, and accessibility while maintaining technical accuracy. Changes: - Simplified academic language (Category Theory → Overview) - Added concrete examples with actual byte arrays - Improved consistency across Double, Float, and [UInt8] extensions - Enhanced namespace documentation with usage examples - Added DocC cross-references throughout - Replaced emphatic language with clear technical descriptions - Maintained all technical accuracy and IEEE 754 conformance details All files updated: - IEEE_754.swift: Enhanced module-level docs with performance notes - Double+IEEE_754.swift: Improved all method documentation - Float+IEEE_754.swift: Mirrored Double improvements for consistency - [UInt8]+IEEE_754.swift: Enhanced initializer documentation - IEEE_754.Binary64.swift: Simplified from academic to practical - IEEE_754.Binary32.swift: Consistent with Binary64 improvements All 174 tests pass.
