Remove emojis from docs; standardize formatting and lists

Replaced all emoji icons in documentation with plain text for a more professional and consistent appearance. Standardized feature lists, headings, and test coverage sections across all implementation and summary files. Updated SECURITY.md to show 4.0.0 support with a Unicode checkmark. Cleaned up VERSION_4.0.0_UPDATE_SUMMARY.md and README to use standard bullets and numbering. All docs now consistently reference version 4.0.0 and 186 tests, improving clarity and accessibility.
