Follow-up to experimental ACP child sessions (#142). A child previously returned to running when any one approval resolved, and cancelling/closing a child could leave permission requests and network waiters alive. This tracks approval tasks per session, keeps requires_action until every pending request resolves, and denies requests before cancelling their waiters when a child stops, finishes, or closes. Closed adapters reject queued late requests. A late client allow result cannot revive an already denied request.

Validation: 26 child/approval/baseline tests pass. New regressions cover two simultaneous pending requests and cancel, parent-close, and child-finish while both are pending, including client replies that deliberately return allow after cancellation. Tests assert denied outcomes and no remaining waiter tasks. Scoped Ruff and diff checks pass.
