RuinedWardrobe

This is the full production hardening pass.

• Removes same-owner bound copies instead of converting them into normal duplicate items.
• Keeps detached armor tied to its source slot until storage is reconciled.
• Makes API saves consume physical armor and refuse occupied wardrobe slots.
• Returns displaced physical armor safely when empty-slot checks are bypassed.
• Validates bound piece metadata before persistence and rejects stacked armor-cell writes.
• Flushes online armor before storage migrations.
• Bounds caches and configuration values, hardens local file paths, and improves async failure logging.
• Shrinks the jar while keeping normal TCP MySQL/MariaDB support.
