Bug Fixes:
- Fixed falling blocks issue during block regeneration due to physics. Blocks no longer fall when regenerated.
- Fixed crop regeneration bug where crops regenerated as seeds instead of fully grown crops when players teleported to another world or logged out. Crops now retain their fully matured state.
- Resolved negative tool damage error.
- Fixed issues with unbreakable items.
- Addressed world spawn and chunk load errors.
- Fixed an issue with region deletion; regions are now properly removed from `regions.yml`, and previously set values of `-100` are no longer used.
- Corrected an issue where regions were not properly removed from the configuration upon deletion.

New Features:
- Enhanced Region Protection Controls:
- BlockBurn Toggle: You can now enable or disable block burning within specific regions for fire protection.
- BucketTake and BucketPlace Control: Control water and lava usage in regions by enabling/disabling bucket actions to prevent unauthorized players from using buckets in protected areas.
- Explosion Protection: Added the ability to enable/disable explosions (TNT, creepers, etc.) inside regions for enhanced security.

*Note: Region protection settings are configurable only through the configuration file, not the in-game GUI.*

Improvements:
- Enhanced block regeneration system.
- Improved item loading functionality.
- Enhanced plugin performance through defined cache variables.
- Added auto-completion for `/regen delete` and `/regen item delete` commands for easier usage.
- Introduced Anvil GUI support for Paper 1.21.1.
