updated documentation for v4.1.223 with new security features

Browse Source 
- Added comprehensive connection security overhaul with advanced mutex framework (15s timeout)
- Added race condition protection via atomic key generation and serialized operations
- Added multi-stage validation pipeline with automatic rollback and precise error phase detection
- Added enhanced MITM protections (key fingerprints, session anti-hijacking, mutual challenges, package integrity)
- Added secure key storage system with WeakMap isolation, private storage, validation, rotation, emergency wipe, and monitoring
- Added production-ready security logging with environment detection, data sanitization, log level control, rate limiting, and memory cleanup

- Updated `public/README.md`: “What’s New” for v4.01.223, expanded to 15-layer security (added layers 13–15)
- Updated `public/SECURITY.md`: added new architecture items; updated supported versions (4.1.x = MILITARY-GRADE, 15 layers); new upgrade recommendation
- Updated `public/doc/SECURITY-ARCHITECTURE.md`: 12→15 layers, added layers 13–15, revised performance (total ~78.5ms), updated dates/versions
- Updated `public/doc/CRYPTOGRAPHY.md`: added `SecureKeyManager`, `SecureLogger`, `ConnectionMutexManager`; updated TOC; updated dates/versions
- Updated `public/doc/API.md`: added Security Framework APIs and usage examples; added TOC
- Created `public/SECURITY_UPDATES_v4.1.md`: comprehensive v4.1.223 security update summary
