Introduce a tested controller for selection mutations, target-mode interception, outbound ordering, Use/PickUp lifetime, and live-incarnation cleanup, plus narrow movement and WorldSession transport adapters.
Move render-hit validation, live target classification, closest-hostile search, selection spheres, use/pickup gates, range checks, and approach parameters behind a read-only App-layer query owner. GameWindow now supplies runtime seams and delegates instead of owning those algorithms.
