feedback5 O10: 自选 operator kits 棘刺, 司霆惊蛰 and 赤刃明霄陈 — every skill, talent, trait and module (stage 1 / 3) at every form

- server/sim/content/kits/ops/op-thorns.js (领主; LOR-X, LOR-Δ), op-leizi2.js (解放者; LIB-X), op-chen3.js (术战者; AFT-X),
  appended to OPERATOR_KIT_FILES; numbers from the composed records (backups.json), mechanics from PRTS and the client's
  battle data (buff templates, charpacks, skill / equip / projectile prefabs, skeleton clips). No engine change; the data
  triggers unchanged (司霆惊蛰 S1 / S2 SEARCH reported, not changed).
- tests: test/content/op_thorns.test.js (12), op_leizi2.test.js (12), op_chen3.test.js (11).
- golden: only diy moved — diy-049 … diy-053 now field the three new kits in every form × module × skill (the diy family
  packs every kitted operator, 12 pieces per battle); the prototype battles moved from diy-049 … 052 to diy-054 … 057 (same
  pieces, new ids); diy-001 … 048 and the roster / bonds / fields / matches / standins families unchanged.
