Update v1.6.6 — Persistent Stats & Safer Reload
• Persistent stats: players’ kills, deaths, hits, and KDR are now saved in stats.yml and kept after restarts.
• Improved /reload: no more item duplication — all config values, slots, and timers reload safely.
• Reinforced PvP override: stronger control against WorldGuard/Essentials/PvPManager/CombatLogX.
• BossBar refresh: colors & styles update live; bars auto-clean on quit.
• Conflict detection 2.0: clearer console tips for known PvP plugins.
• Polish: safer cooldowns, cleaner logs, optimized timers.
• Full support for Java 21 and Paper/Spigot 1.20.6–1.21+
