Enemy hit-reacts: React/Stagger anim tiers off Health-drop edges (the Rukhanka-safe flinch)

SwordCombat React (1.4x, 0.3s pulse) + Stagger (1.2x, 0.55s) as Any-State
states on AC_EnemyTopDown via EnemyRigTools.WireEnemyHitReacts; driven by
EnemyAnimationDriveSystem's cache (now Pos/Hp/ReactUntil/Heavy) off
replicated Health drops. Windup-honesty gate: light reacts require
!IsAttacking (a sub-poise hit never visually cancels a live windup);
the heavy tier tracks the server's B2 poise break (stagger threshold 50
= finisher staggers, light flinches at the locked tuning). Knobs:
HitReactSeconds (0=off) / HitStaggerSeconds / HitReactStaggerDamage.
Replaces the review-cut positional vibrate (Rukhanka inverse-fold no-op).
