feedback5: merge W5AA — community reports of 2026-10-06: the 孤岛风云 prisoners leave the gate confined (grey) and change model as their prefabs do, the 4th attack hits freed; a bounty enemy that dies with no operator behind it pays in 联防 too (the helper whose half it fell on); 忍冬's trigger and 枯朽之种's bounty were already fixed (pinned by tests); DESIGN §25.14 after round 18's §25.13; data/enemies.json regenerated offline on the merged code (round 18's model quirks + the prisoners' clips); golden: vs feedback5 exactly W5AA's moves (26 battles, solo-ABYSS-2, coop2-NORMAL-3, coop3-ABYSS-5, solo-HARD-9-boosted), vs W5AA exactly round 18's boss-pool moves
