Animate enemies: client-derived Rukhanka rigs (Werewolf/Kaiju Husks)

Extends the DR-022 player pipeline to Husk enemies. A Husk is an ownerless
interpolated ghost = structurally a remote player, so the new client-only
EnemyAnimationDriveSystem mirrors PlayerAnimationDriveSystem's remote path:
velocity from LocalTransform-delta (prevPos cache, pruned every frame), facing
from LocalTransform.Rotation (AnimParamMath.PlanarForward), maxSpeed from baked
EnemyStats, IsAttacking from the already-replicated AttackWindup telegraph. No
new [GhostField], no server/asmdef/ghost-hash change.

Monster-mash roster: Werewolf (Grunt), Werewolf-Undead (Swarmer), Kaiju (Brute),
built by the reusable, GUID-preserving EnemyRigTools editor tool (materials +
AC_EnemyTopDown + EnemyAttackWindup clip + 3 rigged prefabs). WaveSystem now
preserves the baked variant Scale (was reset to 1 by LocalTransform.FromPosition).

See DR-023. EditMode 208/208; validated in Play (rigs skin, scales replicate,
locomotion + attack telegraph drive correctly).
