feedback5 R19A: a stunned or frozen enemy is blocked by contact where it stands — an operator redeployed beside a frozen 隐匿 enemy blocks it and so reveals it (GitHub #232, @ccyl; the repro and the cause by @kukiC); golden: 52 scenarios move

ai.js updateEnemy returned on `stunned && !e.hidden` before the contact check (Battle._checkBlock), and 冻结 / 沉睡 / 浮空
set `stun` too, so a held enemy was never checked: an operator redeployed or deployed beside it, a slot freeing up or a
push / pull into contact with a stun all waited for the status to end (0.1.4 had it too). PRTS 异常效果: STUNNED / FROZEN
stop the enemy's moves and attacks and hold no 不可阻挡 (BLOCK_FREE), which SLEEPING / LEVITATE do; 术语释义 冻结 names no
block; 作战机制 §碰撞体积与位置识别: an operator deployed onto an enemy blocks it, a standing one included. The held branch now
runs the same check before it returns (no move, no attack, as before): _checkBlock still refuses 沉睡 / 浮空 / 恐惧 /
不可阻挡, an enemy held short of contact is blocked only once it walks in (the same point as without the status), and the
3 s 隐匿 window after a block's end is unchanged. A block the held enemy already holds is still not re-checked (a reborn()
重生 keeps its blocker, as in 0.1.4: noted as open in §25.22.1).

Golden — in each scenario the first divergence is a stunned or frozen enemy blocked during its status by an operator or
summon it touched with a free slot (traced one by one with an instrumented copy): roster-003, -014, -015, -016, -017,

parent). Docs: CHANGELOG 0.2.0 规则（按官方）, docs/history/0.2.0.md §25.22.1, docs/SIM.md (§1.2 Blocking, stun, freeze),

@@ -69,6 +69,7 @@
 - 萨卡兹穿刺手被晕眩或束缚时停止加速、加速层数清零（减速不会清零，和官方一样）；被阻挡后的第一下额外造成「当前移动速度 × 600」的物理伤害，然后停止加速（社区反馈）。
 - 自制投石机「索敌不受阻挡影响」：被站在排气格栅上（隐匿）的干员阻挡、范围内又没有别的干员时不会攻击，和原版一样；其他敌人仍会攻击阻挡自己的隐匿干员（社区反馈）。
 - 升级调度中心后，新增的商品栏位立即放上新卡，不用等下一次刷新（社区反馈；官方教程「升级后将出现更多的商品栏位」）。
+- 被冻结或晕眩的敌人仍会被接触到的干员阻挡：干员再部署到它身边、或阻挡数空出来时会立即挡住它，隐匿的敌人也随之破隐，不用再等冻结或晕眩结束；沉睡、浮空、恐惧和不可阻挡的敌人仍然不会被阻挡（GitHub #232，感谢 @ccyl、@kukiC）。
