feedback1e WQ: healer tests cast every skill while blocking; rule in headers

Review follow-up for E2 (not reproduced, no behaviour change):
- blockRun fills the skill's SP (and puts the patient back to 5 %) the
  first tick the healer blocks, and tests 2 and 3 assert the skill is
  cast or running while it blocks: all 56 healer loadouts now cast in
  the window (half never did at the default initial SP).
- The reported 炎 boss round makes 录武官's skill ready when she first
  holds 卢西恩 / 不祥幻影 and asserts it is cast or running then.
- The boss test says what it covers: 0 healer damage on all 20 boss /
  hidden fields; healers block 卢西恩 / 不祥幻影 (h07_05) and a
  patrolling 碎铳之簧 once its shield is broken (h08_02); the other
  leaders and parts cannot be blocked by a block-1 unit.
- SIM.md: the healer qualifier follows the "one-line flip" sentence, so
  "This replaces..." refers to the every-blocker rule again.
- ai.js header, Battle.blockedTargets and targeting.js: the blocked-first
  rule is for attacks that hit enemies; a heal attack keeps selecting
  injured allies (PRTS 卫戍协议/帮助).
- PLAYING.md: the healer exception names 咒愈师 as the one that hits.

 attack allies whose collider touches their range circle — centre distance ≤ `rangeRadius` + `ALLY_COLLIDER_RADIUS` 0.25
