feedback1d WL: 源石溶剂 drain is 无来源 true damage; 信仰搅拌机 S3 counters any damage

Player report D1: the 源石溶剂 HP loss should set off 信仰搅拌机 S3 and, next to
莫斯提马, stack 拉特兰 layers on its own. The drain was a Battle.loseHp 流失, which
skips 受击回复 SP and the 重装 TAKE_DAMAGE trigger, and the S3 counter needed an
enemy attack and a target.

Official: PRTS 盟约记录 源石溶剂 "受到60真实伤害" (修正 "并非流失", 备注
"造成无来源真实持续环境伤害"); PRTS 信仰搅拌机 S3 备注 "反击受到任何伤害后均可触发，
无需目标，视为普通攻击"; PRTS 作战机制: 生命流失 skips 反伤 / 受击回复.

- damage.js periodicDamage: the periodic_damage template (源石溶剂, 狂暴宿主组长)
  as 无来源 true damage (shields, damage-taken modifiers, hit effects, 受击回复 SP,
  TAKE_DAMAGE); the credit is unchanged.
- 信仰搅拌机 S3: any damage except 流失 / element 损伤 counters; with no enemy in
  range the counter still spends its bullet.
- Audit, same rule both ways (damage.js isHpLoss): 孽罪奇美拉's aura on operators
  is damage; 雷蛇 战术防御 and 蒂比 S2 / 片场工作指南 respond to any damage
  (PRTS notes); 乌尔比安, 伪装服, 远牙, 录武官's guard and 坚守 thorn chances no
  longer respond to a 流失.
- data/items.json regenerated (源石溶剂 implFormula text only).
