    Universal Silent Aim -> adapted for "Project Remix [Gun Game]" (place 15073271237)
    Executor target: Volt (docs.voltbz.net)

    Why this differs from the generic Universal Silent Aim:
      * Project Remix guns are HITSCAN via the game's own DamageService:Bulletcast /
        :PierceBulletcast (main-thread), NOT workspace:Raycast / FindPartOnRay / Mouse.Hit.
      * Projectile weapons (rockets / thrown / katana) fire via ProjectileService.NewProjectile.
      * Hit registration is CLIENT-AUTHORITATIVE: the weapon resolves the hit part with
        DamageService:GetHitTarget and applies damage with DamageService:Damage itself,
        so bending the cast direction (or projectile velocity) toward a target lands the hit.
      * The generic build hooked game.__namecall / Mouse.__index, which never intercept the
        game's custom cast methods (and the bullet SIMULATION runs inside a parallel Actor VM
        that main-thread hooks can't reach) -- so it did nothing here. This build hooks the
        real chokepoints instead.
