* ContentGuard v4.5 Turbo - Ultra-High-Speed Variant
*
* Optimized for extreme speed to handle hundreds of thousands of real-time messages.
* Target: <0.1ms processing with 50%+ accuracy
* Use case: Massive chat monitoring, real-time stream processing
*
* Architecture:
* - Zero preprocessing
* - Pre-compiled critical patterns only
* - Integer-based scoring for speed
* - No external dependencies
* - No caching overhead
* - Minimal object allocation
