// server/sim/content/kits/ops/op-siege.js — 推进之王 (char_112_siege) 自选 operator kit: 6★ 尖兵 (先锋), an owned-6★ pick
// of the tier-5 and tier-6 自选 slots; every skill, both talents, the trait and both modules at every form.
// Kit contract and the 自选 rules: ../README.md ("How to add an operator (自选)").
//
// Forms (data/backups.json units.char_112_siege, the DIY slot statuses): normal = E2 Lv1, skills at rank 4, no module;
// elite = E2 Lv60, rank 7, the picked module at stage 1 (tier 5) or 3 (tier 6). Potential 0 [ASSUMED: no account].
// Sources: character_table / skill_table / battle_equip_table (zh_CN, as built into backups.json) and PRTS 推进之王
// (talent 修正 "在场时"; 粉碎 备注 "本天赋无视自身的阻回，可响应飞行单位的死亡"; S2 备注 "技能固定动画不受攻击速度影响";
// S3 "攻击间隔增大(+1.0)").
// - Trait (尖兵) "能够阻挡两个敌人": the profession default (block 2). Module SOL-X “糖果盒” overrides it with
//   "阻挡敌人时攻击力和防御力各+8％" (trait bb atk / def): +atk / +def while she blocks at least one enemy.
// - T1 万兽之王 "在场时，所有【先锋】职业干员的攻击力和防御力各+8%": an aura on every 【先锋】 operator of the field (her
//   included) while she is deployed (installAura: the kits' convention for field-wide talents — teammates' pioneers in a
//   shared field too; several sources keep the strongest). SOL-X stage 2+ adds "自身攻击力和防御力额外+N%" (the module
//   talent change's bb, +8 % at stage 3): a self buff on top; the aura value stays the base talent's (talentsBase).
// - T2 粉碎 "周围四格内有敌人倒下时获得1点技力" (talent range x-5: her tile and the four next to it): +sp SP when an enemy
//   dies there — flying enemies too, and under her own 阻回 (PRTS 备注) — never while a timed skill runs (AK: no SP during
//   a skill). SOL-Y stage 2+ raises it to sp (3 at stage 3) "场上随机另一名【先锋】职业干员获得1点技力": the hidden module
//   talent's sp to one other 【先锋】 operator of the field, drawn uniformly [ASSUMED: any deployed other pioneer, a draw that
//   cannot take SP wastes it].
// - Module SOL-Y “初诺” "首次部署时部署费用-4" (hidden runtime_cost −4): the first deployment of a battle costs nothing in
//   this mode ⇒ no effect (as 德克萨斯's 战术快递 elite note); its HP / ATK are in the stats.
// - S1 冲锋号令·γ型 (AUTO, no target): +cost DP at once; an AUTO skill acting on nobody fires as soon as its SP is full
//   (`trigger: 'SP_FULL'`, as 德克萨斯's kit casts the same skill — the owner's AUTO rule, kits/README.md checklist 5).
// - S2 跃空锤 (AUTO, 可充能 2 / 3 次): the next attack hits every enemy around her — the skill range x-5 — for atk_scale × ATK
//   physical and gives cost DP; the data's DEFAULT trigger (an AUTO "next attack" waits for her attack). The AoE is the
//   attack itself, so it reaches the ground enemies a melee attack can [ASSUMED: no source says it reaches air]. The fixed
//   skill animation (PRTS 备注) does not change the sim's attack timing.
// - S3 碎颅击 (MANUAL, 18 / 21 s): attack interval +base_attack_time s (a flat +1.0 on her 1.05 s), each attack at
//   attack@atk_scale × ATK with attack@buff_prob to stun the target attack@stun s.
