More aggressive noise filtering:
1. Anomaly threshold raised from 1.5x to 2x
- 1.5x is too borderline to be actionable
- Now requires genuinely significant deviation
2. Filter out 'Ran diagnostic' and 'Executed command' fallback items
- These are generic summaries that provide no value
- Only show remediations with specific, meaningful descriptions
Goal: If something shows in AI Intelligence, it should demand attention.
