feedback5: merge O23 — 自选 kits for 白铁 (devices, 铁钳号), 娜斯提 (three 支援装置, the built 高台) and 死芒 (复燃 servants, special form); engine (additive): an ally our attacks select (queries / ai, after enemies in target order, never healed); golden: only diy moved

The attack loop (ai.js `acquireTargets`) appends the registered ones standing on the attacker's range after every enemy (their 嘲讽等级 −2 puts them last: one target ⇒ an enemy first; all in range / more targets ⇒ them too) and ranged attacks fly to them; heals, skills that pick their own victims and enemies never select them (the kit gives it `untargetable` against enemies and cancels the damage it takes in its `hit` hook).
