Function calculateMovementSpeed

calculateMovementSpeed(physical: PhysicalAttributes, baseSpeed?: number): number
Calculate movement speed modifier based on weight and leg length.

Korean: 이동 속도 계산 (Calculate Movement Speed)

Computes movement speed modifier based on body weight (inversely) and leg length (positively). Heavier fighters move slower, while longer legs provide faster base movement.

Formula: baseSpeed * (legLength / 95) * (75 / weight)
- Normalized around 95cm legs and 75kg weight
Parameters
- physical: PhysicalAttributes
  Physical attributes of the fighter
- baseSpeed: number = 100
  Base movement speed (default: 100)
Returns number
Modified movement speed
Example
```
const musaSpeed = calculateMovementSpeed(MUSA_PHYSICAL);
// Result: 100 * (95/95) * (75/75) = 100

const jojikSpeed = calculateMovementSpeed(JOJIK_PHYSICAL);
// Result: 100 * (90/95) * (75/85) = ~88.2 (slower)
```
