Packaged Core 1.0.18 fixes a NoSuchFieldError in TidePupfishChunkMixin.
BuiltInRegistries.ITEM is DefaultedRegistry<Item>, not Registry<Item>.
Recompiled the mixin with the correct field descriptor and method owner.
Verified descriptor against the reference used by Tide 2.1.1's own mixin.
20 chunk logic tests pass with the corrected registry type.
All other classes and gameplay data are unchanged from 1.0.17.
Not tested in a full Minecraft runtime.
