Improved DATABASE storage safety by moving upgrade statistic writes to a single background queue and avoiding main-thread refreshes for cached player stats.
Improved optional database compatibility by bundling SQLite, MySQL, and MariaDB drivers only in the database artifact while keeping the default plugin jar lightweight.
Fixed runtime library cache validation so corrupted or mismatched cached jars are redownloaded instead of loaded.
Fixed GUI slot validation so out-of-range slots no longer crash inventory creation.
Fixed enhancement scroll drag handling so scrolls cannot be placed on invalid targets.
Fixed upgrade material slot validation so only configured materials can be placed manually.
