Fix camera target Y position fallback in flock transform

[tracygardner]

Summary

Updated the camera target Y position logic in the flock transform to use the existing mesh target's Y coordinate as the primary fallback before defaulting to the camera position.

Key Changes

• Modified the Y position assignment for tgtPos to check mesh1.target?.y first before falling back to camPos.y
• This ensures that if a target Y position was previously set on the mesh, it will be preserved rather than always resetting to the camera's Y position

Implementation Details

The change improves the behavior when useY is false by maintaining consistency with any previously established target Y values, providing a more predictable camera positioning experience during flock transformations.

Summary by CodeRabbit

• Bug Fixes
  • Improved camera target positioning logic to use the mesh's vertical coordinate when the vertical-axis constraint is disabled, rather than always defaulting to the camera's position. When no mesh target is available, the camera position is used as a fallback. This ensures more accurate and consistent camera behavior when working with constrained camera controls.

📝 Walkthrough

Walkthrough

The api/transform.js file has been updated to modify the camera lookAt special-case logic. When useY is false, the target position's y coordinate now retrieves from mesh1.target?.y with a fallback to camPos.y, replacing the previous behavior of always using camPos.y.

Changes

Cohort / File(s)	Summary
Camera Target Position Logic api/transform.js	Modified the y coordinate source in the target position vector when useY is false, changing from a fixed camPos.y to a dynamic fallback pattern using mesh1.target?.y.
