M1d: creatures, hunting, weapons, food buffs and the hide cloak
- Rabbits, deer and boars with procedural meshes and animated legs, a state machine (idle/wander/flee/charge/dead) and heightmap steering that avoids water, cliffs, the world edge, trees and buildings - Spawner keeps a habitat-based budget around the player (6/4/3) - Melee needs a weapon or tool (club, spear, axe, pickaxe); box sweep hits - Wooden spear (thrust or throw) and crude bow with draw-scaled arrows; projectiles stick in the world as saved pickups - Carcasses: E to butcher for meat, hide and embedded arrows - Boars charge and gore when hit; hurt flash and a brief healing pause - Cooked meat gives Well fed (faster stamina and healing); buffs saved - Hide cloak: wear for warmth, saved, goes in the grave on death - Feathers as meadow pickups (appended, existing save ids unchanged) - New test_creatures_combat suite; run_all.sh gets a per-suite time limit

## Procedural low-poly animals, built from the same helpers as the trees and
|
||||
## items (flat-shaded, vertex colours, no assets).
|
||||
##
|
||||
## Each kind gives a static "body" mesh (torso, head, ears, tail) facing -Z,
|
||||
## one "leg" mesh hanging from the origin down -Y, and the four hip points
|
||||
## the legs pivot on. creature.gd animates the legs.
