Dupe Plugins

[DISCORD](https://discord.gg/7yurBtecrf) A deliberate item-duplication toolkit. It ships dedicated modules for roughly a dozen known Minecraft dupe exploits — item frames (including glowing frames), grindstones, anvils, TNT, fireballs, cactus, droppers, crafters, observer+piston setups, shulker boxes on donkeys/llamas, death-related item duplication, and a "command dupe." Each one is gated by a tiered permission system (vip/premium/admin), with configurable trigger probability and an output multiplier — i.e., it's set up so server owners can sell tiered access to duplicating items, not just patch or detect dupes. An "EconomyFix" illegal-item scanner. This half does the opposite job: it scans for unbreakable, overstacked, illegally-enchanted, or otherwise unobtainable items and can auto-remove or auto-fix them, presumably to clean up after the dupe modules (or after other exploits) get used. Other bits: a GUI config interface, English/German translations, an update checker, and telemetry that's enabled by default (sends server name, OS, and version every hour to the plugin author's update-checker service unless disabled in config.yml).
