Tractor Beam Elevators

Changelog 1.0.1

• Replaced consumable Speed Upgrades with a reusable Speed Controller. 
• Right-click either linked pad to increase speed; crouch-right-click to decrease it. Speed adjusts in steps between 1× and 10×, updating both pads together.
•  The controller now shows its downgrade texture while crouching and restores its upgrade texture when you uncrouch.
• Breaking either pad resets the surviving pad’s speed. Newly connected pairs start at base speed.
• Added gentle centering while you have no horizontal movement input, helping keep you aligned in the elevator shaft. The pull stops immediately when you start moving.
