## What changed
- Use the shared approval-policy check for unified exec sandbox escalation so
`require_escalated` commands can prompt when granular `sandbox_approval` is
enabled and remain rejected when it is disabled.
- Add an approval scenario covering sandbox escalation with granular approvals
enabled.
