Analysis Engine

Argus uses a rule-based analysis system:

interface AnalysisRule {
  name: string;
  analyze(steps: Step[]): Finding[];
}

// Built-in Rules:
- DuplicateReadRule       // Detects duplicate file reads
- UnusedReadRule          // Finds unused tool outputs
- RetryLoopRule           // Identifies retry patterns
- FailedToolRule          // Tracks failures
- ContextPressureRule     // Memory pressure detection
- CompactionDetectedRule  // Context compression events
