feedback7: merge fb7-owner-sim — community reports via the owner: 白铁's 铁钳号 opens only the skills that act on it (圣约送葬人 spends and stacks), 伊内丝 S3 after a 突袭 jump, 引星棘刺 alchemy units as HP regen (不屈者 / 禁疗), 不可对空 effects spare flying allies (炎佑), 望's 跟子 at battle start, 香槟炸弹 unhealable / no HP loss (owner decision) and not set off by unrevealed 隐匿 or sleeping enemies

- Grok review: MERGE AFTER FIXES — the HIGH finding (skills opened on the device but spending nothing) fixed on the branch
  (69d791f9: skills.js allyTargetsOk, per-kit allyTargets flags).
- Golden union OK; broad node --test 5500 (5499 pass, 0 fail, 1 skipped); lint 0 errors.
