feedback1 WD: 逐火 embers can be beaten, 转译基底 changes form before it can die

Player reports after 0.1.0:
- #8 深池逐火战士 / 精锐战士 / 护卫: every knock-out is a 1 s 重生 (invulnerable,
  unblockable, immobile), then a walking, disarmed, 隐匿 hit-count ember that a
  blocker can target and beat; it stands up with full HP after 10 s (PRTS talent
  text). The old ember stood still, stealthed and unblockable, so nobody could
  ever target it and every 逐火 enemy leaked. 假想敌：再生's puppet walks on and
  stays unblockable.
- #5 转译基底·α: its original form cancels every damage instance; the 4th
  physical / arts hit or a block starts a 2 s change into 寻仇者 / 特战术师 /
  幽灵 (Mode_*_Passive, 寻仇者 rage below half HP, 特战术师 two targets). The
  armed forms attack through the engine (profile.dmgType). It used to die in its
  first form.
- Render: units.js FORMS switch the models' clip sets (A_Die_B/C/D then B/C/D,
  Die then Idle_2/Move_2/Die_2, Revive), driven by the 'phase' kind or the fx
  `form`; a noMove enemy is drawn standing.

 Other renderer rules from research 07 §5.4–5.5:
 - **Choosing the model:** Front when the unit faces right or down; Front mirrored when facing left; Back when facing up.
 - **Attack speed:** set the attack `timeScale` to `duration / attackInterval`.
