Function generateVulnerabilityHeatMap

generateVulnerabilityHeatMap(
    width: number,
    height: number,
    currentHour: number,
    stance: TrigramStance,
    meridianStates: Record<string, number>,
): readonly (readonly number[])[]
Generate vulnerability heat map for entire body

Korean: 취약성 히트맵 생성 (Vulnerability Heat Map Generation)

Generates a 2D vulnerability map for visualization or analysis. Returns vulnerability scores (0-1 normalized) for a grid of positions.
Parameters
- width: number
  Width of the heat map grid
- height: number
  Height of the heat map grid
- currentHour: number
  Hour of day for meridian calculations
- stance: TrigramStance
  Current trigram stance
- meridianStates: Record<string, number>
  Meridian disruption states
Returns readonly (readonly number[])[]
2D array of vulnerability scores (0-1 normalized)
Example
```
const heatMap = generateVulnerabilityHeatMap(
  100, 700,                   // 100x700 body map
  14,                         // 2 PM
  TrigramStance.GAN,          // Mountain defensive stance
  { lung: 1.0, heart: 1.0 }
);

// Access vulnerability at position (50, 100)
const vulnerability = heatMap[100][50]; // 0-1 normalized value
```
