PaperMC migration, Entities and Logging

[integr-dev]

This pull request introduces several improvements and refactors across the codebase, focusing on modernizing APIs, improving logging, and simplifying code. The most significant changes are the migration from BungeeCord to Adventure text components, a complete overhaul of the logging system for better formatting and clarity, and the removal of the example item TestItem. Minor improvements include utility additions and API updates for command arguments and server access.

API Modernization and Refactoring

• Migrated text component system from BungeeCord (BaseComponent, ComponentBuilder) to PaperMC's Adventure (net.kyori.adventure.text.Component), including updated usage in the README.md and command code. This affects how hover and click events are handled and how colors are applied. [1] [2] [3] [4] [5]
• Refactored server access throughout the codebase to use Backbone.SERVER instead of directly referencing Bukkit, improving testability and abstraction. This change is reflected in command arguments and core logic. [1] [2] [3]

Logging Improvements

• Replaced the previous logger implementation with a custom BackboneLogger that formats log output with ANSI colors and timestamps, and disables parent handlers for cleaner output.
• Added log messages for registering and unregistering event listeners for better traceability.

Codebase Simplification and Utility

• Removed the example/test item TestItem and related registration logic to streamline the codebase and focus on production features. [1] [2]
• Added a Utils.tryOrNull helper function for safe exception handling, used in plugin initialization. [1] [2]

Documentation and Presentation

• Updated README.md to reflect the new text component system and GUI framework, and added status badges for CI, release, commit, and license. [1] [2] [3]

Minor Improvements

• Improved error handling and control flow in item replication commands.
• Updated copyright headers.

These changes collectively modernize the project, improve developer experience, and lay the groundwork for future enhancements.
