refactor(runtime): own interaction transactions

Move use throttling, appraisal identity, queued interactions, and exact post-arrival pickup state beneath RuntimeActionState. Keep App as the picker, movement, transport, and retained-presentation adapter while preserving retail send and UseDone ordering. Add reset, disposal, GUID-reuse, callback-reentrancy, and transport-failure coverage.
