Adds a new DB function to look up claimed tasks by worker identity (task_queue_id, worker_group, worker_id). This will be used by the queue's worker-removed-resolver to resolve tasks when a worker is removed.
Resolves claimed tasks as exception/worker-shutdown when a workerRemoved Pulse event is received from worker-manager. Follows the same post-resolution logic as ClaimResolver (publishing taskException, scheduling retries, updating dependency tracker).
Adds the worker-removed-resolver as a new background process in the queue service. Subscribes to worker-manager's workerRemoved Pulse events to resolve orphaned tasks immediately. Includes tests for retry, no-retry, already-resolved, and no-tasks scenarios.
