IGrabPresenter.Grab(GrabEvent) only; the binder's Transform and velocity resolvers go. TractorBeam
presents a running grab (aims at Started's TargetPosition, emits at Power, dark otherwise). FieldDriver
draws its tendril from GrabEvents alone with a real-time phase clock over each event's PhaseDuration and
writes no transform and destroys nothing; its grab times move to FieldTester, now the scene's stand-in sim
that owns its pickup's timeline and pose. ItemPickup keeps its label lit while held. ImpactPresenterSmoke
becomes CapabilityPresentationSmoke with a grab section; its two untracked-ship expectations follow
DrawsAt since contact-hud. Builds (Unity 6000.3.24f1 batchmode: smoke ok, scene opens, no missing script).
