Added

• Smarter Placeholder Parsing: Improved world name detection in PAPI placeholders to correctly handle world names containing underscores (e.g., world_nether, my_custom_world).
• Standardized Defaults: Updated worlds.yml template to ensure features like anvil default to true, preventing accidental global blocks after installation.

Changed

• Thread-Safe Architecture: Refactored ConfigManager to use ConcurrentHashMap for all internal world states, ensuring reliable performance in multi-threaded environments.
• Tab-Completion Logic: Refined tab completion to prevent irrelevant feature suggestions when using subcommands like help or reload.
• Feature Consistency: Standardized crafting-table and crafting under a unified crafting feature key across filters, listeners, and config.

Fixed

• Dead Code Cleanup: Removed unused fields and redundant special-case checks in command validation to improve maintainability.
• Improved Disposal: Enhanced resource cleanup during plugin disable to eliminate potential memory leaks from stale references.
