Get next task

Atomically pick AND claim the single highest-priority task ready for you to work — the queue's dequeue. Returns one task (already claimed and set to in_progress) or {task:null} when nothing is workable. Prefer this over list_my_tasks+claim_task in a fleet: it closes the race where two agents grab the same task between listing and claiming. Skips done/wont_do/pending_approval/plan_proposed tasks, tasks blocked by an unfinished dependency, paused tasks, and tasks another agent holds an active lease on. When {task:null}, the response includes a hidden breakdown (blocked/done/wont_do/pending_approval/plan_proposed/needs_input/paused/claimed_by_other counts) so you know whether to stop, go unblock something, or wait for a lease to lapse. There is no way to make this hand out a paused task: list_my_tasks({include_paused:true}) can show you one for reporting, but nothing claims one. Like list_my_tasks, this ranks across every workspace the account belongs to unless you pass workspace_id (from list_workspaces).
