Simple Discord Whitelist

Security and Architecture Overhaul

• Enhanced Encapsulation: In CorePlugin.java, managers (PlayerManager, BotManager) are now better protected. Public getters have been removed to prevent other plugins from accessing internal data.

• Dependency Injection: Listeners and commands now directly receive the managers they need via their constructor, resulting in cleaner code and easier maintenance.

Discord Intent Optimization

• Security Minimalism: The bot now only uses the Server Members Intent. The "Message Content" and "Presence" Intents have been disabled for greater privacy and efficiency.

New Discord Features

• Automatic Whitelist Removal: If a member loses their role on Discord, their Minecraft whitelist is automatically revoked.

• Slash Commands: Complete management via Slash Commands (no need to read private messages).
