Bug Fixes

Fixed: Shulker Box Interaction Blocked
Issue: Players could not interact with Shulker Boxes (open, take items) when SmartPets was installed.

Root Cause: GUI event handlers were using overly broad title matching (contains()) that could accidentally match other inventory types. Additionally, handlers weren't checking the inventory type before canceling events.

Solution:

1. Added InventoryType.CHEST check to all GUI handlers - Shulker Boxes use SHULKER_BOX type
2. Changed title matching from contains() to more specific patterns (startsWith(), endsWith(), equals())
3. Applied fix to all affected GUI classes

Fixed: MySQL Connection Timeout Issues
Issue: "No operations allowed after connection closed" errors when using MySQL storage, especially after periods of inactivity.

Root Cause:

1. Connection validation only checked isClosed() but didn't test if connection was actually usable
2. MySQL server-side timeouts weren't handled properly
3. No automatic retry mechanism for connection failures

Solution:

1. Enhanced Connection Validation: Added isConnectionValid() method that tests connections with SELECT 1
2. Improved MySQL URL: Added robust connection parameters:
   • connectTimeout=60000 & socketTimeout=60000 - Longer timeouts
   • maxReconnects=3 & initialTimeout=2 - Automatic reconnection
   • allowPublicKeyRetrieval=true & serverTimezone=UTC - Compatibility
3. Automatic Retry Logic: Both executeAsync() and queryAsync() now retry up to 2 times on connection errors
4. Connection Refresh: Forces new connection creation when stale connections detected
