Added /ss commands:
These commands allow you to quickly swap and save indefinite amount of skins in your server!
- `/ss clone <skin_name> --player <player_name>` → Capture your (or another player's) current skin and save it as a named preset
- `/ss list` → View all saved skin presets
- `/ss swap <name>` → Apply a saved skin preset to your character
- `/ss delete <name>` → Remove a saved skin preset
- Needs OP, or otherwise permissions ss.clone, ss.list, ss.swap, ss.delete.
- Each skin is stored as a Model asset (`SS_MODEL_<name>.json`) + skin data (`SS_SKIN_<name>.json`) under `exports/skins/<name>/`
