feedback5 O23: 自选 kits for 白铁, 娜斯提 (with their 支援装置) and 死芒 (with her 悲叹的仆役); ally targets for 白铁's 铁钳号·原型机

- kits/ops/op-ironmn.js — 白铁 (char_4072_ironmn): S1 / S2 / S3, 战地工程师 (device stock 3, CRA-X +1, refilled at each
  deployment; a device that left comes back on its tile after its redeploy time, paying its cost, one stock, while he stands;
  his devices leave with him), 节约经费 (prob 0.7 / CRA-X stage 3 0.9), CRA-X (stock, costs, stage 3 SP +0.2/s), CRA-Y
  (redeploy times, stage 3 ASPD +6 on device-buffed operators); the device kits 白铁™多功能平台 (S1 ATK +12 % ×2.5 / 3 in S1;
  S2 1 SP / 3.5 s, 2.5 / 2 s in S2, 0.4 % / s 流失 ×2) and 铁钳号·原型机 (an ally target: damage cancelled, 1 SP per hit,
  a 工匠's hit heals 1 %; its skill −2.5 % then 230 / 260 % + 110 / 120 % within 1.1 of 白铁's ATK; 团结的力量 ×0.8
  physical behind it). Exports the shared 工匠 device helpers.
- kits/ops/op-nasti.js — 娜斯提 (char_4212_nasti): S1 / S2 / S3, 前方施工 (stock; CRA-X stage 3 first device −3, combined
  ranges), 注意安全 (10 % 庇护, 15 % + 1 SP / 6 s for her and our ranged operators once a ranged enemy appeared), CRA-X; the
  device kits “质检专员”, “监工专员” (3 / 8 HP, its S2 pulses of SP and her barrier) and “应急承重小组” (小工程师 + the 高台 it
  builds and levels).
- kits/ops/op-necras.js — 死芒 (char_450_necras): S1 / S2 / S3, 复燃 (summon on the kill tile or a random tile of her range,
  upgrade at 3), 回光黯淡, the trait (the enemies her summons block are her targets; SOC-X ×1.15), SOC-X stage 3; the
  悲叹的仆役 kit and its special form (S3).
- Engine (additive): Battle.setAllyTarget / allyTargetsInKeys / isAllyTarget (battle/queries.js); ai.js acquireTargets puts a
  registered ally target of the range after every enemy, performAttack flies ranged attacks to it. Nothing changes while
  none is registered: every golden family but diy unchanged. docs/SIM.md §6 documents it.
- kits/index.js: the three files appended to OPERATOR_KIT_FILES.
- Tests: test/content/op_ironmn.test.js, op_nasti.test.js, op_necras.test.js, test/sim/feedback5-o23-engine.test.js.
- Golden: only diy moved — diy-106 … diy-109 re-chunked (the new operators' configurations come before the prototypes),
  diy-110 … diy-114 new.

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).
