feedback7 R22-OSIM: 白铁's 铁钳号·原型机 counts like an enemy for a non-heal skill's automatic start; golden: unchanged

Community report relayed by the owner: 圣约送葬人 hitting 白铁's device spent no bullet and gained no layer.
Our attacks already selected the device (Battle.setAllyTarget, damage cancelled), but every skill start
condition counted enemies only, so her MANUAL ammo skill (DEFAULT) never opened. The owner's rule of
2026-10-08: a registered ally target in range counts like an enemy for a non-heal skill's auto start.

- skills.js `_allyTargetIn`: DEFAULT (about to attack, the initial range; SEARCH / ACTIVE_RANGE through
  it), CUSTOM_RANGE, SKILL_RANGE, GDGLOW_SKILL_2 (anywhere) and the content trigger ranges. Heal skills
  never count it (禁疗). It stays out of enemiesInKeys / canTargetEnemy.
- 雪猎's empty-magazine S2 cast counts it too; allyTargetsInKeys takes a Set of tile keys.
- 白铁™多功能平台 stays no target. Kits whose own selectors pick enemies (陈 S3, 艾丽妮 S2 guards,
  蕾缪安 S3 locks) are unchanged.

Tests: test/sim/feedback7-allytarget-cast.test.js (4; 3 fail on the parent).
