Review PR #159 (cross-owner reports_to)

tsk-kr6aygtbakvd cancelled chore

Independent review of https://github.com/oliver-zehentleitner/maity/pull/159 contract: cross-owner reports_to needs the subordinate owner's human-only consent, warning, revocable, cross_owner marker, grants nothing. Check escalation via routing (can the foreign agent pull cards, answer requests on behalf?), consent routing, revocation races. Deliver review_result to oz-agent-a.
