Orkuncakilkaya 67d477af77 ludic.wildlife: pin every transition of the 15 WILD_* states and the dice each draws (phase 27.2a)
Sixteen test programs under tests/*_pins_test.ludic, on today's code, each one tick from a set
state through the public step (wildlife_tick_ground / _bird / wildlife_tick, wildlife_release,
wildlife_new): the state it goes to, its timer, and how many of the package's rolls it took and
which (the next roll is read off a newborn's yaw, compared with a stream of the same seed). IDLE,
WANDER, ALERT, WARY, FLEE, CHARGE, GO_DRINK, GO_FEED, DRINK, APPROACH, EAT, TRAPPED, FLY, LAND,
PERCH; the droppings' roll before them; the newborn's seven (eight for a bird); what the step
leaves alone. tests/pin/ holds the shared step, the dice reader and two species of its own (a tame
horse, a crow that never lands on its own). Compiled, not run here: 27.2 holds to them unchanged.

# perch_pins_test.ludic - phase 27.2a: a bird coming down and on the ground as it stands. Gliding in,
# down and within 2 m it PERCHes for 8 + 16 r0 s; anyone within its flee, or 20 s over its time,
# lifts it (FLY, 20 + 40 r0 s); on the ground its time up or anyone within its flee lifts it too
