feedback3: merge W3A — 联防 carries HP ratio and SP only (GitHub #82); down operators take part in the 联防 devour (players' reports, owner's decision); 不屈 on 撤退 / 替身 switches; SP recovers during stun (洛洛 S2)

+  // [ASSUMED: one such deployment at a time, spent by her next deployment whatever brings it]. Tier 2 (+sp SP to every
+  // operator on the field) stays a knock-out effect: its own line ("地面干员被击倒时使场上所有干员技力+5") was not corrected.
