* Apply knockback displacement to defender position
*
* **Korean**: 밀침 적용 (Apply Knockback)
*
* Updates the defender's position based on knockback physics calculation.
* The knockback displacement is applied in the direction of the attack vector
* (attacker → defender), respecting arena boundaries.
*
* **Physics-First Architecture**: Both positions and knockback displacement
* are in meters. Arena bounds are centered at origin (0, 0) with extent
* ±worldWidthMeters/2 in X and ±worldDepthMeters/2 in Z.
*
* @param result - Combat result containing knockback data (in meters)
* @param defenderPos - Current defender position (in meters)
* @param arenaBounds - Arena boundary limits with meter dimensions
* @returns Updated defender position after knockback (in meters)
*
* @example
* ```typescript
* // 10m × 7.5m arena, player at x=2m knocked back 2.5m to right
* const newPosition = applyKnockbackDisplacement(
* result, // knockback.displacement.x = 2.5m
* { x: 2, y: 0 }, // Current position: 2m from center
* { worldWidthMeters: 10, worldDepthMeters: 7.5, ... }
* );
* // Returns: { x: 4.5, y: 0 } (2m + 2.5m = 4.5m, within ±5m boundary)
*
* // Same knockback but would exceed boundary
* const clampedPosition = applyKnockbackDisplacement(
* result, // knockback.displacement.x = 2.5m
* { x: 4, y: 0 }, // Current position: 4m from center
* { worldWidthMeters: 10, worldDepthMeters: 7.5, ... }
* );
* // Returns: { x: 5, y: 0 } (4m + 2.5m = 6.5m, clamped to +5m boundary)
* ```
