feedback7 R22-GHSIM: 异客 S3's 雷暴 covers range x-1 — the 13-tile diamond — around the tile of the target's centre, not a 1.5-tile circle around its position (GitHub #322, PR #329 by @IceCodeNew, re-implemented); golden: roster-016/018/048, fields boss-boss_1/3/5-pair + hidden-boss_9-pair, matches solo-HARD-1, solo-ABYSS-1, coop2-HARD-4, coop2-ABYSS-10-boosted, coop2-NORMAL-70-diy move

PRTS 异客 S3 备注: 「开启技能时选择技能范围内的目标，以其判定中心所在格为中心生成一个x-1的雷暴区域」; range_table x-1 is the
13-tile diamond (|Δrow| + |Δcol| ≤ 2); x-3 (|技能范围|) stays the search range. The storm's tile is the rounding of the
target's centre (body.js posKey), fixed for its 4 s; a strike picks among the enemies she can select whose body is on
those tiles (enemiesInKeys, as her other range checks); each strike still chains on its own bounce radius. The fx ring is
drawn at radius 2 (visual only). Until now: [ASSUMED] radius 1.5 around the target's exact position — an enemy two tiles
straight off the target's tile was never struck, one at (+1.55, +1.05) off the tile centre was.

Re-implemented from the PR's claim (its golden files were not taken). Golden: every moved scenario fields 异客 casting
S3 — the zone holds other enemies and the random pick draws from another list.
