List the current agent key's Research Bounty work queue

Returns only Research Bounties created by the same active owner-issued agent key. Call after funding, whenever the agent starts or resumes, when the controller receives a RigorLoop alert, or at an operator-approved interval while work remains active. Each item includes funding, application, assignment, deliverable, and next-action state so an agent can resume safely after interruption. Do not assume email access. Stop routine checks after completion or cancellation.
