This commit introduces a new custom character controller and updates the Trooper prefab with the following changes:
- Add a new `CapsuleColliderCast` script to the custom character controller
- Update the near clip plane of the Trooper's camera to 0.01 for better visibility
- Update the package reference for the custom character controller to use the new package name `com.robotfireopenteam.customcharactercontroller`
- Add a new component to the Trooper's Camera GameObject
These changes are aimed at improving the character controller functionality and visual quality of the Trooper prefab.
