The publish GitHub Actions job failed during Javadoc aggregation because a field-level Javadoc block in AdvancedCorePlugin used @return, which is only valid on methods. This PR removes that invalid tag so Javadoc generation can proceed.

• Root cause

  • maven-javadoc-plugin failed on AdvancedCorePlugin.java with invalid use of @return for a field Javadoc block.

• Code change

  • Updated AdvancedCore/src/main/java/com/bencodez/advancedcore/AdvancedCorePlugin.java.
  • Removed @return from the Javadoc above vaultHandler (a field), preserving the descriptive text.

• Why this is minimal

  • Single-file, comment-only change.
  • No behavioral/runtime code changes.

/**
 * Handler for Vault integration.
 * 
 * @return the vault handler
 */
@Getter
public VaultHandler vaultHandler;

/**
