- Fix advancements disappearing: use PreparedStatements for all SQL with
user data (advancement JSON contains chars that broke string-concat SQL),
add null safety for advancement file
- Fix multi-server kick: run doPlayerConnect synchronously instead of async
(players could join before the duplicate check completed)
- Fix Curios disappearing: clear slots AFTER validating data exists (not
before), use CuriosCache for dead players on logout instead of empty API
- Fix Sophisticated Storage items: add storeSophisticatedStorageItems() and
restoreSophisticatedStorageItems() to sync packed barrels/shulkers/chests
- Anti-duplication: clear all inventories before restoring from DB on join
- Fix tick counter: remove LevelTickEvent (fired per dimension = 3x too
fast), merge heartbeat into ServerTickEvent
- Fix connection leaks: use try-with-resources for all QueryResult
- Fix logout order: save data BEFORE marking player offline
- Skip auto-save for dead/unsynced players to prevent saving empty data
