BetterEnd

Changes

• Clip worldgen terrain reads to the write zone, and fit canopies to the room they have
• Move End getDrops overrides onto loot tables, and gate bulb vine behind shears
• Emit the vanilla loot additions as data
• Move end-city treasure loot into a datagen-emitted table

Fixes

• Backport the chunk-sweep cave surface coat from 26.3
• Sulphuric lake deep-water peek still read past the write zone
• Sulphuric cave ported from a cross-chunk feature to a structure
• Smaragdant caves were bare and too low; lake and geyser read past the write zone
• End worldgen randoms were raced or unseedable
