feedback7 R22-OSIM: a skill that 白铁's 铁钳号 opens now acts on it — 蕾缪安 S3 / 艾丽妮 S3 / 陈 S2 / 引星棘刺 S2 spend on it, skills that pick enemies only stay closed; golden: unchanged

Grok's review of the 铁钳号 change (HIGH): the device opened every non-heal skill, but kits that pick their victims
with enemiesInKeys only were spent on nothing — 蕾缪安 S3 went active with 0 locks, 艾丽妮 S3 and 陈 S2 struck nothing,
引星棘刺 S2 threw at the empty far tile. Audit: every skill of every chess (loadouts) and of the 自选 pool, placed with
only the device in range; of the 351 skills the device opened, 67 never touched it.

- skills.js `allyTargetsOk`: the device counts for a skill's start only if the skill acts on it — SkillSpec
  `allyTargets` (true / false) from the kit, else [ASSUMED] a skill acting through the unit's own attacks (timed and
  still attacking, or a cast that is the next attack) on a unit that attacks. An onStart-only cast or a no-attack timed
  skill picks enemies itself and waits for one (德克萨斯 S2 剑雨, 锡人 S1/S2, 铃兰 S3 … about 50 skills).
- Spend on the device (allyTargets: true; its kit cancels the hits, its 受击回复 counts): 蕾缪安 S3 locks it and spends
  her bullets (ammoUsed, so the per-bullet layers come) and shells it; 艾丽妮 S3 strikes it; 陈 S2 draws on it after
  every enemy; 引星棘刺 S2 throws onto it and its pulses hit it. queries.js allyTargetsInRadius for their areas.
- Explicitly closed ([ASSUMED], allyTargets: false): 普罗旺斯 S2 (never shoots above 80 % HP), 卡涅利安 S1 (charged: no
  attack), 山 S2 (blocked enemies), 余 S2 / S3, 迷迭香 S3 (blocked only), 荒芜拉普兰德 S1 / S2 (drone locks), 淬羽赫默 S1–S3
  and 遥 S1–S3 (heal attacks), 机械师 S3, 珊比 S2 / S3, 陈 S3 / 艾丽妮 S2 (their guards already refused).
- 雪猎's empty-magazine cast back to enemies only (its S2 does not act on the device).
Re-audit: 281 skills open on the device alone and all act on it (蕾缪安 S3 through her locks); none of those that
acted on it before stopped. Docs: SIM.md, design/engine.md, PLAYING.md.

Tests: test/content/feedback7-allytarget-kits.test.js (5; all fail on the parent).
