docs(teleport): TDD implementation plan — priority residency + fade cover
6 tasks: (1) StreamingController priority-apply, (2) PhysicsEngine residency
query, (3) TAS drives transit + outdoor hold-until-resident (retire the
TeleportArrivalController driver), (4) fullscreen fade overlay, (5) cell-march
lbX hardening, (6) verify + strip the tp-probe. Reuses the dormant
TeleportAnimSequencer as the transit driver; worldReady gates on the
priority-applied destination landblock.
