//! Traffic Obfuscation Module
//! 
//! This module provides traffic pattern obfuscation to prevent fingerprinting and traffic analysis.
//! It disguises traffic patterns by adding padding, changing packet sizes, and introducing
//! dummy traffic to make it harder for adversaries to identify the actual communication patterns.
