AnimalWeights

Animals gain a hidden weight (0-8) based on how well they're kept. Weight scales
the items and XP they drop when killed, so spacious, well-built farms out-produce
crammed 1x1 cram boxes - and neglected animals get sick and stop breeding.

Based on the "Animal Weights" suggestion by u/Axoladdy on r/Minecraft:

How weight works

Every few minutes each tracked animal is scored on four husbandry conditions:

Condition	Met when...
Light	light level >= 14 where it stands
Water	a water source is within a few blocks
Grazing	it stands on grass or moss
Stretching	no other mob is crammed into its space

The more conditions met, the higher the animal's target weight; its weight drifts
toward that target over time. A crammed animal can't climb past weight 2, and one
with no space, no light, and no water sinks to 0 - sick.

What weight does

• More drops & XP. A maxed weight-8 cow drops roughly +7 beef, +7 leather, +7 XP
  over vanilla. Drops trend up naturally near water and around villages.
• Sick animals (weight 0) can't breed and show a visible "unwell" cue.

Tracked animals

Cow, Mooshroom, Pig, Sheep, Chicken, Rabbit, and Goat - all configurable.

Commands & permissions

Command	Permission	Default
/aw check - weight + conditions of the animal you're looking at	animalweights.check	everyone
/aw set <0-8> - set an animal's weight	animalweights.admin	op
/aw reload - reload config	animalweights.admin	op
/aw info - plugin info	animalweights.admin	op

Configuration

Everything is tunable in config.yml (weight range, evaluation interval, each
condition's threshold/radius, drop & XP scaling, the sick effect, tracked-mob list),
then /aw reload.
