Changelogs

Added:

• Automatic safety backup before every restore
• Discord webhook notifications for backups
• Atomic (crash-safe) file restore

Fixed:

• Blacklisted items could be placed into the EnderChest via hotbar number-key swap — now blocked.
• /ec search ignored the "require permission for command" setting — it now respects ec.use like every other command.
• Switching pages could freeze the server (especially with MySQL) because saving ran on the main thread — page switching is now fully asynchronous.
• /ec reload could hang the server for up to 10 seconds while waiting for open chests to save — it no longer blocks the main thread.
• MySQL chest lock had a race condition — two networked servers opening the same chest at once could both acquire the lock. The lock is now claimed atomically.
• MySQL restore now runs in a proper transaction with rollback — a failed restore no longer leaves the database half-wiped.
• Offline player name lookups in /ecsee, /ecshare, /ec clear, /ec uninvite, /ec rowinfo, and /ec pageinfo no longer risk freezing the server on unknown names (resolved asynchronously now).

Removed:

• Dead/unused internal code.
• Unused enderchest.command.use permission node.
