Fix: attack animation sank the model into the floor (Rukhanka partial-clip collapse)

Browse Source 
An attack clip that keys ONLY the Root bone makes Rukhanka collapse every un-keyed bone (Hips/Spine/legs) to identity for the duration of the state -> the body folds halfway into the floor (player MeleeSwing + enemy Attack; writeDefaultValues does NOT prevent it -- confirmed since even a pure yaw, which is height-preserving, still sank). Fix: build the attack clips FROM the full idle pose (every bone keyed) + a Root YAW twist on top, so nothing is un-keyed. Applied to both runtime clips (PlayerMeleeSwing/EnemyAttackWindup) and both editor recipes (PlayerRigTools/EnemyRigTools) so rebuilds stay correct. Operator-verified in Play.
