/**
* Time-windowed event deduplication utility.
* Suppresses repeated identical events within a configurable window.
* Used by SecurityMonitor and SecurityTelemetry to prevent log flooding.
*
* @example
* ```ts
* const dedup = new EventDeduplicator(60_000, 500);
*
* if (!dedup.shouldSuppress('injection\0/api/query\0SQL detected')) {
* logger.warn('New security event');
* }
* // Same key within 60s → suppressed
* dedup.shouldSuppress('injection\0/api/query\0SQL detected'); // true
*
* // Check how much noise was filtered
* const stats = dedup.getStats();
* // { suppressedCount: 1, processedCount: 1, cacheSize: 1 }
* ```
