Added

• Performance and reliability improvements to balance fast-path caching and background persistence.

Changed

• Reduced DB contention and improved fast-path caching semantics for balances to provide more consistent immediate responses under load.
• Withdraw fast-path: added per-key striped locking to prevent concurrent over-reservations.
• Shutdown ordering: background persistence flush now runs before closing JDBC pools to guarantee pending deltas are persisted.

• Configuration: moved MySQL tuning keys into performance.mysql in the main config.yml. The plugin now prefers performance.mysql.* with fallbacks to mysql.* in config-mysql.yml; documentation and default configs were updated.

• Added MySQL tuning options and safer defaults: background persistence batching/queueing settings and additional Hikari pool tuning keys (leak-detection-threshold-ms, validation-timeout-ms, initialization-fail-timeout-ms, auto-commit). JDBC params now include UTF-8 encoding by default.

• Security: /eco command permissions tightened. New granular permission nodes added: ezeconomy.eco.give, ezeconomy.eco.take, ezeconomy.eco.set, ezeconomy.eco.gui (GUI opens require ezeconomy.eco.gui), and ezeconomy.eco remains the umbrella admin node. Console execution still allowed.

Fixed

• Race conditions where multiple concurrent withdraws could exceed the persisted balance.
• Background flush failures during shutdown caused by closed connections.
