Warp: decouple from player SimulationState (fix camera/targeting regressions)

Browse Source 
Pulsing the player's SimulationState (DropZoneAcquired->Translocated) to trigger
the translocation sphere regressed everything else that dial drives in our
reconstruction -- the camera flipped to inside-view, targeting/firing gated off,
shadow pass glitched. That dial is load-bearing; co-opting it was wrong.

Replace with a self-contained render one-shot: btplayer.cpp respawn calls
BTStartWarpEffect(dropZoneOrigin); the effect plays its own collapse->expand and
touches nothing but the render. No SetSimulationState, no DropZoneLocation write,
no per-entity renderable walk (the tree's BTTranslocationRenderable objects are
now inert). Scale capped 30/40 (authentic 100/150) so the sphere -- centred on
your own reinsertion -- doesn't envelop the camera; tunable via BT_WARP_SCALE.

Smoke-verified 2-node: warp fires on each respawn (collapse 31->5, expand ->35),
repeats, respawn cycle intact, no crash. Camera/targeting restored (state pulse
gone).
