* Cryptographically Secure Random Number Generator

* CRITICAL: Math.random() is predictable and can be fingerprinted by Microsoft
* This module uses crypto.getRandomValues() for unpredictable randomness
*
* DETECTION RISK: Math.random() produces patterns that bot detection can identify:
* - V8 engine uses xorshift128+ algorithm with predictable sequences
* - Given enough samples, the seed can be reconstructed
* - Microsoft likely monitors Math.random() distribution patterns
*
* SOLUTION: crypto.getRandomValues() uses OS entropy sources (hardware RNG)
* making it impossible to predict future values from past observations
