The freshly converted hunter's body was hidden for the settle window via a
WaitForSeconds coroutine. If the object was disabled or the converting owner
disconnected mid-settle, the coroutine was stranded and _renderGate stayed
true forever, leaving the avatar invisible on every remote.
Replace it with a frame-driven Time.time deadline (_renderGateUntil) lifted
in UpdateVisibility, which runs every frame the component is active and can
never get stuck. Remove the coroutine and the now-unused System.Collections
using. Visible behaviour in the normal case is unchanged.
