Act as a senior Minecraft Spigot/Paper plugin developer. Create a production-ready plugin for the latest Minecraft version called “SYSTEM”. This plugin must combine Lifesteal + Headsteal with a secure Prison System using Multiverse worlds. The system must be fully protected against exploits, duplication, farming, and data loss. 🔹 CORE HEART SYSTEM Every player starts with configurable permanent hearts. When a player kills another player: Killer gains +1 permanent heart (up to max 30). Victim loses -1 permanent heart. Kill farming must not give rewards. 🔹 HEAD DROP SYSTEM (ANTI-DUPLICATION) Player heads ONLY drop when: The victim’s permanent hearts reach exactly 0. The victim is sent to prison. Heads NEVER drop on normal deaths. Each player can only have ONE active head at a time. All heads are bound to the player UUID. Heads have a unique ID and digital signature. Duplicated, renamed, or glitched heads are automatically invalid. Used heads are permanently invalidated. 🔹 PRISON SYSTEM (MULTIVERSE WORLD) When hearts reach 0: Player is teleported to a Multiverse world named “prison”. Player is locked to 1 heart. Player cannot leave prison by commands, portals, exploits, or glitches. Player is blocked from main worlds. Show a GUI and Title message: “You are imprisoned. Survive here to earn freedom.” Prison world rules: Hard difficulty Limited resources No teleport No /home, /spawn, /tpa No external inventory access No item transfer 🔹 TIME-BASED REDEMPTION SYSTEM Prison time is counted in REAL server time (not playtime). Default: 5 real days (configurable). Time is saved even if server restarts. After timer ends: Automatically free player Restore configurable hearts Teleport to main world Broadcast release message 🔹 HEAD ALTAR FAST-RELEASE SYSTEM Create a configurable altar structure. When a valid head is placed on altar: Instantly free the imprisoned player Restore partial hearts Remove prison timer Consume the head Invalid heads do nothing. 🔹 ANTI-FARM & ANTI-ABUSE SYSTEM Detect repeated kills between same players. Block heart gain and loss for farming patterns. Add configurable kill cooldown. Track UUID/IP patterns. Log suspicious activity. 🔹 SAFE DATA STORAGE Store all data in: YAML + optional MySQL Auto-save, shutdown save, backup system. Crash-safe recovery. 🔹 FAIL-SAFE SYSTEMS Auto-regenerate prison world if missing. Safe defaults if data is corrupted. 🔹 ADMIN CONTROL PANEL Commands must use a configurable prefix (default: /system): /<prefix> reload /<prefix> prison <player> /<prefix> free <player> /<prefix> hearts <player> <set/add/remove> /<prefix> reset <player> /<prefix> status <player> 🔹 PREFIX & BRANDING SYSTEM All commands and messages must use a configurable prefix. Example: [SYSTEM], [MyServer], [HardCore] Prefix must be editable in config.yml. Support color codes. 🔹 CONFIGURATION SYSTEM Configurable: Max hearts Start hearts Prison duration World names Command prefix Chat/message prefix Altar structure Messages Cooldowns Anti-farm limits 🔹 PERFORMANCE & QUALITY Must support 200+ players.
