After the first run, edit:

Useful options:
```toml
[stacking]
entity_ids = ["minecraft:cow", "minecraft:pig", "minecraft:sheep", "minecraft:chicken"]
stack_radius = 8.0
minimum_group_size = 2
max_stack_size = 64
scan_interval_ticks = 40
show_stack_name = true
separator_item_id = "minecraft:stick"
consume_separator_item = false
separated_no_stack_ticks = 200
```
Rules:
- Only entity ids in `entity_ids` stack.
- Only mobs within `stack_radius` merge.
- A new stack starts only when `minimum_group_size` matching mobs are close enough.
- Baby mobs stack separately from adults.
- Sheep stack separately by wool color and sheared state.
- Shearing a woolly sheep stack drops wool once per sheep represented in that stack and damages shears for each sheep sheared.
- Milking a cow stack with multiple buckets fills one milk bucket per milkable cow, limited by the empty buckets in hand.
- When a chicken stack lays an egg, it drops one egg per adult chicken represented in that stack.
- Right-clicking a stack with `separator_item_id` splits one mob out of the stack.
- A manually separated mob waits `separated_no_stack_ticks` before it can stack again.
- Right-clicking a stack with a named name tag names one mob split from that stack, and named mobs do not stack.
- Feeding a stacked adult animal consumes one breeding food per breedable mob in that stack, limited by the item count in hand.
- Stacked animals remember how many represented mobs are in love, then breed in pairs inside the stack or with a nearby compatible love stack.
- Mobs in a stack that already bred have their own cooldown, so partially feeding a stack does not block the whole stack.
- When a stacked mob dies, vanilla loot and XP drop for the killed mob, then the remaining count stays as a new stack.
- Fire, lava, campfire, and magma-style deaths only remove one mob from the stack; the remaining stack gets brief protection so it does not instantly chain-die.
