feedback5 WL: 生命回复速度 is not 治疗 — the 吟游者 trait, 调香师, 瑕光 S2, 铃兰 S3 and 锡人 give an hpRegen buff, so 无法被友方治疗 / 禁疗 units get it and 治疗加成 does not scale it (GitHub #96 / #137)

PRTS: 分支特性信息 吟游者 「特性为基于自身攻击力来增加受益者的“生命回复速度”属性」 (魔王, 浊心斯卡蒂); the 备注 of 调香师 熏衣草,
瑕光 S2, 铃兰 S3 and 锡人 S2 「生命恢复的提供方式为增加目标的“生命回复速度”属性…不受治疗加成和禁疗影响」 (铃兰: none in the
first second, refreshed every second); 异常效果 禁疗 「增减生命回复速度…的效果不会被识别为治疗类能力」. These were heals from
the provider, which damage.js refused on 收割者 / 不屈者 / 武者 (noHeal) and under 禁疗 — 隐德来希 gained nothing under 魔王.
This is the separation proposed in PR #135 by @SpiritedAwayCN, written anew (the PR's patch is not used):
- professions.js bardRegen: the trait is an hpRegen buff per bard refreshed every 0.25 s; 魔王's 微尘 ×1.5 goes through
  its `bardRegen` hook (both 魔王 kits); 浊心斯卡蒂's pulse and the 海嗣 token use it too.
- 调香师 (every ally), 瑕光 S2 (the skill range, removed at its end), 铃兰 S3 (from the first full second, removed at its
  end), 锡人 (per 炼金单元, its cached ATK): hpRegen buffs instead of battle.heal.
- damage.js: a `regen` tick takes no healing multiplier and a heal hook cannot change its amount (no 治疗加成 on any
  生命回复速度); 流明's 凡人之愿 and 华法琳's S1 bonus skip a regen tick of their own.
Direct heals are unchanged (still refused / scaled); 魔王 S3's redistribution and 纯烬's HoT are untouched. Other
per-second recoveries without such a note stay heals (引星棘刺, 塞雷娅 S3, 流明 / 纯烬 HoTs; 余 闲云隐市 and 天马之盔 left open).
