Complete the anomaly indicator integration for all three metrics:
- CPU: EnhancedCPUBar (already done)
- Memory: StackedMemoryBar (new)
- Disk: StackedDiskBar (new)
All three metric bars now show a pulsing indicator (e.g., '2.5x↑')
when the current value is significantly above the learned baseline.
Severity colors:
- Critical (>4σ): red
- High (3-4σ): orange
- Medium (2.5-3σ): yellow
- Low (2-2.5σ): blue
This is 100% deterministic - no LLM involved. The indicators appear
automatically based on statistical deviation from learned baselines.
