Overworld Vanilla Structures

Overworld Vanilla Structures 1.0.4

• Fixed structure generation to avoid hard terrain cuts and ugly chunk-edge carving.
• Added generated-chunk safety buffer before placement to prevent partial structures at borders.
• Reworked Hunter Cabin layout: corrected roof shape, interior cleanup, and proper bed placement.
• Improved loot reliability for structure chests/barrels using vanilla loot tables with safe fallback loot.
• Fixed /locate behavior so unknown targets now forward to vanilla /minecraft:locate instead of blocking vanilla structures.
• Improved locate tab-complete fallback so vanilla locate suggestions keep working when custom matches are not used.
