WorldWeaver

Features

• Let a feature fit its geometry to the write zone

Fixes

• End cave-biome band sat too low and switched biomes too often
• ModelProviderMixin is client-only, so declare it in the client array
• Pottable traits keep the latest registration, not the first
• solid_in_dir searched backwards out of its chunk
• Surface-condition noise contexts were cached in a plain HashMap
• Nether surface materials were drawn from a running random
• The same seed did not reproduce the same world
• Keep the biome bootstrap context alive across the tag phase so /reload works
