Copper Age Backport

[1.20.1-0.0.7] - 2025-11-22

Fixed

• Waxed Copper Chests are now recognized by Copper Golems as source containers
• Barrels surrounded by blocks (only front face accessible) are now correctly detected by Copper Golems

Added

• Separate tag system for container types: golem_target_chests and golem_target_barrels
• Tag-based barrel detection for modpack compatibility
• Container-specific blocking checks (chests need space above, barrels only need front face free)
• Copper Golem AI now accepts both chest and barrel tags as valid target containers
• Automatic sound detection based on container type (Copper Chest, Barrel, or Regular Chest sounds)
• Spawn Egg now uses color-based rendering (0xB87333 and 0x48D1CC) instead of texture files

Changed

• Updated CHEST_COMPATIBILITY.md with separate documentation for chests and barrels
• Updated datapack example to include golem_target_barrels.json
• Improved barrel accessibility logic for better pathfinding in tight spaces
