NPC Logistics

What's new in 1.1.6

New roles

• Dairy Worker (equip a Bucket) — milks cows, manages a bucket economy: takes empty buckets from the deposit chest, returns milk buckets after each round. Auto-tags nearby cows on activation.
• Chicken Collector (equip a Feather) — scans for naturally dropped eggs near the jobsite and deposits them to the chest.

Livestock system

• Per-herd collar colours — each NPC worker gets a unique ring colour
  derived from their identity. Dave's flock and Jones's flock are visually
  distinct when viewed through Work Goggles.
• Charged Livestock Tags — right-click an NPC worker with an unstamped
  tag to charge it with that worker's herd colour. Animals you tag manually
  will then match the worker's ring colour.
• Untag gesture — sneak + right-click a tagged animal with an empty hand to release it.
• Collar rings gated behind Work Goggles — rings are now only visible
  while wearing Work Goggles (previously always visible).
• Stray threshold tightened — animals are nudged back at 20 blocks from their pen (was 32).
• Tagging restricted — manual and auto-tagging now applies to sheep,
  cows, pigs, and chickens only (rabbits were accidentally included before).

Pathfinding

• Workers no longer route over chest or barrel lids mid-path. A custom
  navigation layer marks chest/barrel tops as obstacles so workers walk around them naturally.

Shepherd

• No-gate fallback — if no fence gate is found near the jobsite, the
  shepherd operates free-range and navigates directly to the jobsite centre
  instead of stalling.
