Crystal Chaos Core

Fixes a server crash when dropping an item from a full inventory during the protected transition from looting to the battlefield. Overflow is held safely, returned when inventory space opens, and released exactly once through normal battle-death handling.

The native inventory-click regression reproduced the beta.6 crash and passes with this fix in the full modpack. Validation passed: 383 logic tests, 148 native core tests, 148 full-modpack server tests, and a graphical client/integrated-world check, all from the same source.

Minecraft 1.20.1, Forge 47.4.10, Java 17.

This is a stability update. Expanded progression, permanent unlocks, lobby shortcuts and classic Hunger Games are separate work and are not included in this file.
