feat(combat): cues de hit react + som punch + camera shake (cliente UE)

3 GameplayCueNotify_Burst BPs (taxonomia Lyra GameplayCue.Zeus.Combat.Hit.*):
  GC_Combat_Hit_React   -> PlayAnimMontage AM_HitReact_Light no alvo
  GC_Combat_Hit_Impact  -> SpawnSoundAtLocation SW_Punch_Cartoon na pos do alvo
  GC_Combat_Hit_Self    -> ClientStartCameraShake CS_HitReact no PC do alvo

Assets novos:
  AS_HitReact (+ AM_HitReact_Light/Medium/Heavy) -- montages de reacao
  SW_Punch_Cartoon -- SFX de impacto (0.3s)
  CS_HitReact -- LegacyCameraShake (osc 0.35s, pitch/roll/locZ)

DT_Abilities recriado (RowStruct ZeusAbilityDataRow): rows Dash+Kick com
AbilityClass + ActivateCueTag GameplayCue.Zeus.*. GC_Kick/GC_Dash com tags
renomeadas pro prefixo GameplayCue.* (filter do Asset Picker).

ZeusServerTags.ini: regenerado via ZeusTool tags sync (106 tags canonicas).

Source/Combat/ZeusAnimNotifyState_BodyHitWindow: AnimNotifyState que abre a
janela de hit detection (FootR capsule) durante o swing do Kick.

+ *  AnimNotifyState que liga o HitCollider de uma parte do corpo durante a sua
+ *  janela no montage. NotifyBegin liga + NotifyEnd desliga -- define o HIT
+ *  WINDOW do golpe melee/arma branca.
+ *
+ *  Generaliza para qualquer parte do corpo via EZeusHitSource:
+ *    - FootR / FootL  -> chute   (capsule attachado em foot_*_Socket)
+ *    - HandR / HandL  -> soco    (capsule em HandGrip_*)
+ *    - WeaponR / WeaponL -> arma branca (capsule em weapon_*)
+ *
+ *  === Como usar ===
+ *
+ *  No editor de um AnimMontage (ex: AM_Kick_Montage):
+ *    1. Encontrar o frame onde o membro comeca o movimento de impacto.
+ *    2. Right-click na track de notifies -> Add Notify State -> Zeus Body Hit Window.
+ *    3. Definir Source = FootR (ou HandR pra soco, WeaponR pra arma, etc).
+ *    4. Arrastar o range pra cobrir o arco completo do golpe (ex: frame 8 a 18
+ *       em 30fps = ~330ms de janela).
+ *
+ *  Pq AnimNotifyState e nao AnimNotify pontual:
+ *    - AnimNotify dispara em UM frame -> nao da' pra detectar entradas no
+ *      capsule durante a janela.
+ *    - AnimNotifyState tem NotifyBegin/NotifyTick/NotifyEnd. Pra "ligar
+ *      collider de frame X ate Y", e' o pattern correto.
+ *
+ *  === Replicacao ===
+ *
+ *  Roda LOCAL em cada cliente. Cliente do ATIVADOR liga capsule local + reporta
+ *  overlap via opcode MELEE_HIT_REPORT pro server. Server valida e aplica dano +
+ *  dispatcha cue Kick.Target pra todos no AOI do alvo.
+ *
+ *  Proxies de outros clientes tocam o montage via GameplayCue replicado (visual)
+ *  mas o capsule deles roda no PROXY que e' Pawn local de outra coisa -- nao
+ *  importa, o reportador autoritativo eh quem ativou a ability.
