feedback7 R22-GHSIM: 假想敌：骨刺 targets as PRTS writes — its normal attack ignores its block (by priority, not the blocker first), never a flying unit, and its 3 hidden targets come from its normal attack's reach (PR #365 by @Sukvii, sim part, each line checked against PRTS); golden: roster-018 moves

The sim lines are the PR's (content/enemies/invisible.js kitBoneSpike: profile blockFree and canTarget, the hidden
selection over rangeRadius + the ally collider), so the contributor is the author of this commit; the maintainer side
checked each rule, kept the engine's single target when the hidden list is empty, and wrote the tests.

Official: PRTS 假想敌：骨刺, 级别0 天赋 (on the page since 2025-11, PRTS editors): 「自身普通攻击索敌不受阻挡影响」 「不会攻击
飞行单位，隐匿（解除阻挡0秒后恢复）」 「隐匿期间可同时攻击3个目标」; enemy_database's level description 「隐匿；隐匿状态下同时攻击
3个目标。」 (the handbook line keeps 「数个目标」) — the 3 is no longer [ASSUMED]. blockFree works as for 自制投石机 (a 隐匿 /
迷彩 blocker is no target); canTarget as the engine's other 不会攻击飞行单位 enemies; the hidden 3 are picked among the
allies its normal attack could hit (ai.js attackTargets: rangeRadius + ALLY_COLLIDER_RADIUS, PRTS 作战机制 碰撞体积) — they
were picked within the bare 2.0. Stealth back 0 s after a block was already so.

Golden: roster-018 — the 骨刺 in it lands one more attack (on 异客; dmg 2434 → 2771), the same move PR #365 reported.
