Troll UI

This system adds a “troll panel” for your game:

- Players can spectate other players with a smooth camera.

- While spectating, they can pick a troll and use it on the target.

- Trolls are sold as DevProducts (one purchase per use, with support for saved “credits”).

- Includes cooldowns, feedback notifications, and R6 ragdoll support.

The goal is to be:

- Easy to plug into an existing UI.

- Easy to add/remove troll types without touching the core logic too much.
