feedback7 R22-OSIM: 香槟炸弹 no longer goes off on an unrevealed 隐匿 enemy (nor a sleeping one) — it selects like the other contact traps; golden: bond-yanShip-high, coop2-HARD-4 move

Community report relayed by the owner: 「有人反馈香槟炸到没有破隐的隐匿敌人了」. Reproduced: a 隐匿 walker crossing
琳琅诗怀雅's bombs set them off (both kits checked hidden / flying / untargetable only). The rule: PRTS 作战机制 §隐匿
"隐匿效果使得获得该效果的单位无法被任何敌方的能力索敌选中…要选中隐匿的目标，则该单位自身需拥有无视隐匿的效果"; 异常效果 lists
隐匿 and 无敌 among the 无法选择 effects (沉睡 = "无敌且无法行动", gamedata_const ba.sleep). Neither the 香槟炸弹 page nor
琳琅诗怀雅's S2 carries a 无视隐匿 / 无视可选性 note, and the other contact traps of the sim (多萝西's 共振装置, 望's 棋子)
already select through canTargetEnemy.

Now both kits go off on a ground enemy canTargetEnemy accepts (tokens.js CHAMPAGNE_TRIGGER): a 隐匿 enemy sets one off
once it is revealed (反隐) or blocked (its 隐匿 lifts), a sleeping one once it wakes (until now the bomb was spent on it
for no damage). Placement is unchanged (it already aimed at selectable enemies only).

Golden: bond-yanShip-high and coop2-HARD-4 (bombs under 隐匿 enemies of rounds 10–11 — 隐形弩手组长, 访问团强攻冠军,
重弩突袭者 — and sleeping ones of round 7 — 宿主士兵, 粉碎攻坚手 — now wait).

Tests: test/content/feedback7-champagne-stealth.test.js (2; both fail on the parent).
