detectEmergingThreats(
    currentThreats: readonly {
        category: PoliticalThreatCategory;
        level: ImpactLevel;
        evidence: readonly string[];
    }[],
    baselineThreats: readonly {
        category: PoliticalThreatCategory;
        level: ImpactLevel;
    }[],
    detectionDate?: string,
): EmergingThreat[]
Detect emerging threats by comparing current threat levels against a baseline.

A threat is considered "emerging" when:
- The category was not present in the baseline (new threat), OR
- The current impact level is higher than the baseline level
Escalation rate:
- rapid: escalated by ≥ 2 impact levels
- moderate: escalated by 1 level
- slow: new (no baseline) or minimal change
Parameters
- currentThreats: readonly {
      category: PoliticalThreatCategory;
      level: ImpactLevel;
      evidence: readonly string[];
  }[]
  Current threat dimensions with their impact levels
- baselineThreats: readonly { category: PoliticalThreatCategory; level: ImpactLevel }[]
  Baseline (historical) threat dimensions for comparison
- OptionaldetectionDate: string
  ISO date string for the detection timestamp (defaults to today)
Returns EmergingThreat[]
Array of EmergingThreat objects sorted by escalation rate (rapid first)
