BallSaboteur

Adds a new runtime-registered sabotage item to Super Battle Golf.

The item reuses the Orbital Laser pickup and targeting flow for testing, but it does not overwrite the vanilla Orbital Laser item. When used on another player, their ball becomes a cube until they take a sufficiently long stroke and the ball comes fully to rest, at which point it returns to a sphere.

Current prototype behavior:

Registers a new runtime ItemType and injects matching ItemData.
Reuses Orbital Laser targeting so it locks on to players the same way.
Randomly converts a share of Orbital Laser spawns into Ball Saboteur for testing.
Includes an optional F8 debug grant hotkey for fast iteration.
