feedback5 WE1: enemy attacks strike at their damage frame; a short stun before it cuts the swing (GitHub #187 point 1, #170)

PRTS 状态机: ATTACK / COMBAT "每帧检查异常状态，若有则切换到异常状态的状态"; PRTS 异常效果 STUNNED (the state machine
leaves the attack), DISARMED "正在进行的普通攻击将被中断". The strike frame is data/enemies.json attackAnim.hit.

- ai.js: attackWindup = the clip's strike frame (half the clip when none is named), shortened with the clip like the
  stand; the cooldown counts down to the strike and the swing (enemy.swing) starts when it reaches the wind-up with a
  target in reach (attackTargets, shared with the frame) — steady-state strikes stay one interval apart. An enemy whose
  cooldown ran out before it had a target (walking, just blocked, a cut swing) swings from the start: the whole wind-up.
- A stun / freeze / sleep / 浮空 / hiding, 缴械, 恐惧, 战栗 while blocked or losing every target cuts a swing short of its
  frame: no strike, the next swing starts from its wind-up. A stun in the cooldown only pauses it; a strike already
  made stays made. No clip known (36 of 249 kinds): no wind-up, the old rule. [ASSUMED] targets re-taken at the frame,
  a cut swing does not spend the cooldown, enemy heals keep no wind-up.

Golden: 275 of 283 scenarios moved — roster all 49; bonds 41 of 46 (unchanged: bond-arcaneShip-high,
bond-kjeragShip-low, bond-maniShip-low, bond-skillfulShip-high, bond-swiftShip-low); fields all 22; matches all 18;
standins all 10; diy 135 of 138 (unchanged: diy-027, diy-029, diy-087) — every battle where a clip-carrying enemy meets an
operator: the first strike of a contact waits its wind-up, stuns cut swings (the cut alone moves 55). With every
attackAnim stripped from the data the corpus is byte-identical to the previous commit (nothing else moved). Bot
matches: solo-HARD-2 now wins, coop2-NORMAL-8-serverrun now loses; the other 16 keep their result.

Tests: test/sim/feedback5-enemy-swing.test.js (new, 6). Updated on purpose: feedback2-enemy-attack-stand.test.js (it
locked the instant first strike), enemies_bosses.test.js (沉沙 / 新硎's cleared interval, 帝国的甲胄, 斩胄之剑 / 破胄之锤 wait
for the frame). test/sim, test/content, test/match pass. Docs: SIM.md, DATA.md (attackAnim), ASSETS.md.
