Resolve #15 and some code cleanup

Code Cleanup

• Improved code organization.

Structural Changes

• Moved script loading and unloading responsibilities to a dedicated script manager class.
• Scripts now load when the ServerLoadEvent is triggered, enhancing plugin performance and startup.

Breaking Changes

• Breaking: onEnable and onDisable methods have been removed from the script lifecycle.
  • Recommendation: Use onLoad and onUnload as alternative methods for initialization and cleanup.
