v0.0.17: Enemies come alive

Every regular enemy and both bosses are now fully animated: they walk, wind up, strike, flinch and die, and their hits land when the blow connects.
Readable attacks: enemies glow and swell as they wind up a hit (easy to spot from the commander view too), the Golem cracks as its armour wears, and boss specials line up with their warning rings.
Hit feedback: ice chips fly off where you hit, big hits stagger enemies, and slowed enemies frost over.
The Almanac's enemy pages show each enemy animated on a stand, with how to spot its attack.
Fixes: the Cryo Mage's hands stay on its arms, the Runner's bite looks natural, your pick swings in your right hand, and the original crystal icons are back.
Boss weak spots now register correctly for every player in co-op.
Big waves run smoother: about 66 fps with 300 enemies at High on an RTX 2080 Ti.
Hollow signs are easier to read, and the same map seed now gives the same waves.
Closed exploits: gun spam, off-map orders and stored-up cooldown bursts.
