Follow-up on @fangliquanflq's opt-in (#84775): after the profile-scoping fix (#94560) the container cache key is resolved in _resolve_container_task_id, so the shared key must unify profiles there too — 'shared:<key>' for every session of every opted-in profile AND for CLI/no-session runs. Delivery adds the shared sandbox layout as the first translation candidate. Empty key keeps strict per-profile isolation; SSH ignores the key entirely.
