StopTimer

What's Changed

✨ Features

• Template System: Added templates.yml to manage predefined shutdown reasons (e.g., /stopserver 5m t:update). Default templates are automatically generated on first run.
• Dynamic Reasons: Fully supported %reason% placeholders across all notification channels including Title, Chat, BossBar, Discord, and Kick messages.
• BossBar Customization: Added the ability to dynamically customize BossBar color and style directly within config.yml.
• Enhanced Tab Completion: Added smart auto-complete support for r: (custom reasons) and t: (templates). Typing t: will now list all available template names.

🐛 Bug Fixes

• Shutdown Crash: Fixed a NoClassDefFoundError that occurred when kicking players during server shutdown. This was caused by the plugin classloader being closed before anonymous inner classes could be loaded. Refactored legacy Runnable tasks into Java 8 Lambdas to ensure seamless execution.
