New Features

• Recipe Unlock System: BlockShips recipes now unlock when players complete a configurable advancement (default: smelt_iron)
• Automatic Recipe Granting: Players who already have the required advancement will receive recipes when they join the server
• New Config Option: Added recipe-unlock-advancement setting to customize which advancement unlocks BlockShips recipes

Bug Fixes

• Fixed Ship Persistence: Ships now properly persist across server restarts. Previously, ships were being destroyed during shutdown before Minecraft could save them
• Fixed destroyall Command: The command now properly cleans up YAML storage files when removing ships
• ProtocolLib Warning: Added a warning message when running BlockShips commands if ProtocolLib is not installed

Technical Changes

• Added ShipRegistry.clear() method that clears the in-memory registry without destroying entities, allowing proper persistence
• Improved shutdown handling to preserve entities for natural Minecraft persistence
