feedback6 R21F: enemy animation states, the client part of PR #275 by @xcdoge re-implemented — the resolver gives an enemy every numbered skill clip (anims.skills; the caller's first index stays the primary, operators unchanged, 宴's PREFAB_SPINE_ROLES fix kept), the stun spellings Stun_1 and Dizzy_Begin/Loop/End, a separate run role (Run_Begin/Loop/End); the renderer walks an enemy faster than moveSpeed 1 on its Run cycle (猎狗pro, 深池侦察犬 ×2; [ASSUMED] threshold), swaps an enemy's skill clip on a cast event (UnitView.setSkillSlot; a form in force is kept), and plays the 重生 of 巨大的丑东西 (Revive, then the fleeing 大祭司 Idle_2 / Move_2 / Stun_2) and 自在 (Revive_01); data/assets.json regenerated offline: 18 enemies gain anims.skills, 6 anims.run, 3 a stun clip (巨大的丑东西, 斩胄之剑, 破胄之锤), nothing else; the sim's cast slot (a new event) is not part of it; golden: unchanged
